1.1 Students learn to identify the role of enzymes in metabolism, describe their chemical composition and use a simple model to describe their specificity on substrates. Most people would know that some animals (like frogs, snakes and lizards) are a€?cold-bloodeda€? and that when the weather is cold, these animals are less active than when ita€™s warm.
Each enzyme has a unique shape - it is this shape that means it will make just one reaction go. Enzymes are not usually used up in chemical reactions - they can be used over and over, so they can be present in tiny amounts. Enzymes are difficult to study in high school but there is one in saliva that we can study. Explain why our bodies need to make large amounts of digestive enzymes (like pepsin) but only tiny amounts of other enzymes (like hexokinase, which is present in every cell and catalyses the breakdown of glucose to glucose 6-phosphate).
This experiment is important to addressing the skills outcome H11 (a€?A student justifies the appropriateness of a particular investigation plana€?). I hope you have a picture of many chemical reactions occurring in your own body right now, each one occurring because of the presence of tiny amounts of enzymes. So, it is important that the temperature and acidity in your body has to be kept at the right level. Maybe you can think of some changes that occur in your body when the temperature gets too low! The first step to prevent your death is for your body to recognise the change in your body temperature. I have only considered what happens when there is a danger of you over-heating but there are many aspects of your body that have to be kept constant - for example, oxygen, sugar and water levels in the blood. Nerve impulses travel very quickly, and travel from one small part of the body to another small part. Hormones travel relatively slowly in blood, from an endocrine gland to a number of target organs.
An example might be the hormone adrenalin, travelling from the adrenal glands above the kidneys to skin (constricting blood vessels), the pacemaker in the brain (increasing heart rate), the liver (increasing the level of glucose in the blood) and many other organs. At the Mid-Atlantic ridge, a€?black smokersa€? raise the temperature of the ocean above 100oC without the water boiling (because of the very high pressure). There are other organisms that thrive in temperatures close to the freezing point of water. The temperatures at which organisms are found and the range over which they can survive is because of the enzymes in their bodies. A Grylloblattid - (Grylloblatta bifratrilecta) an insect related to crickets and cockroaches that lives in snow.
Leta€™s make our ectotherm the impressive but relatively harmless (if left alone) Red-bellied Black Snake (Pseudechis porphyriacus). Comparing our ectoderm (Black Snake) and endoderm (Wombat) it is clear that both have behaviours and bodies that help them to survive extremes.
Your textbook does not give any examples of plants responding to temperature change - only adaptations to temperature extremes -so Eucalypts have drooping leaves which helps them to avoid overheating when the Sun is high; deciduous trees drop their leaves which helps them to avoid frost damage. Responses of plants to temperature change are not common but there has been great interest from horticulturalists over several hundreds of years in the ability of Rhododendron spp to curl their leaves in response to temperature change. Most people would know that some animals (like frogs, snakes and lizards) are a€?cold-bloodeda€? and that when the weather is cold, these animals are less active than when ita€™s warm.A  Why is this? Enzymes are not usually used up in chemical reactions - they can be used over and over, so they can be present in tiny amounts.A  But most importantly, they only work under special conditions - a narrow temperature range and a narrow pH (acidity) range. That usually doesna€™t happen because things happen in your body to cool your body.A  You sweat, surface veins open up so that blood flows closer to the cooling air, and you breathe more often releasing warm our from your lungs. This is a practical investigation involving second-hand research.A  Before you start it, you should read these notes. I have only considered what happens when there is a danger of you over-heating but there are many aspects of your body that have to be kept constant - for example, oxygen, sugar and water levels in the blood.A  For each, there are receptors that detect the changes and a control centre (usually in the brain) that counteracts the change. Nerve impulses travel very quickly, and travel from one small part of the body to another small part.A  An example might be from a fingertip to a very small part of the brain when we touch something. There are other organisms that thrive in temperatures close to the freezing point of water.A  For example, there are bacteria-like cells that grow on snow turning it red (to produce a€?watermelon snowa€?). On the other hand, individual organisms can generally survive in a fairly narrow range.A  For example, tropical fish die in cold water, yet antarctic fish would die in tropical waters. Choose an ectothermic animal species, an endothermic animal species and a plant species.A  Dona€™t forget the advice about second-hand research, especially to acknowledge your sources. Your textbook does not give any examples of plants responding to temperature change - only adaptations to temperature extremes -so Eucalypts have drooping leaves which helps them to avoid overheating when the Sun is high;A  deciduous trees drop their leaves which helps them to avoid frost damage. These chemical react to make new chemicals and to absorb, release or turn one kind of energy into another.


Many more chemical reactions than usual are happening and so much more heat than usual is being generated. If the car is not fitted with cruise control, we maintain a constant speed by watching the speedometer and adjusting the pressure on the accelerator pedal. For example, if we play a hard game, a temperature sensor detects an increase and adjustments are made to lower the temperature. There are temperature sensors (a€?thermoreceptorsa€?) in the hypothalamus of the brain that recognise the dangerous temperature rise. The brain sends nerve messages to many parts of the body to counteract the rise in temperature. You may remember from your Year 10 Science studies, that messages are sent around the body in 2 ways: nerves or hormones. Warm water fish have enzymes that work best at warm temperatures; cold water fish have enzymes that work best in cold temperatures. In cooler weather or at night, when it is less active and therefore more vulnerable to predators, it hides. However, because it can maintain its body temperature within a narrow range, wombats can remain active over a much wider temperature range. There are lots of keys (substrate molecules) but they can only open one lock - only one enzyme will act on it.
Your body temperature could rise too far, enzymes could easily be destroyed and you would die. If the cara€™s speed increases, by going downhill for example, we notice that the speed has increased by looking at the accelerator then adjust the speed by taking some pressure off the accelerator. Your body temperature is rising, there is a danger of your enzymes being destroyed and the vital chemical reactions stopping. There are also temperature sensors in the skin that send nerve signals to the hypothalamus. Sweat glands are stimulated, veins in the skin dilate (open up), your breathing rate increases and you may feel like you have to leave the field to rest.
They occur on a tiny scale, they happen dissolved in water and they only happen when another kind of chemical - an enzyme is present.
For most parts of most living things, it is close to 7.) Notice that the scale is the opposite to what you might expect - low pH is acid and high pH is base.
In winter, they often feed in the snow (see photo) but can return to the burrow and warm up.
Their shape gives them a small surface area to volume ratio, helping them to retain body warmth. THESE VERY SAME ENFORCEMENT AGENCIES, WHO HAVE SWORN TO PROTECT AND SERVE, OUR COUNTRY, AND CITIZENS ,ARE BUT SOME, OF THE CORRUPT,GREEDY TRAITORS .ENGAGED IN THE TYRANNY AND TORTURE.

Henning Witte, and Melanie Vritschan, three experts from the European Coalition Against Covert Harassment, revealed recent technological advances in human robotization and nano implant technologies, and an acceleration of what Melanie Vritschan characterized as a a€?global enslavement programa€?.Shift from electromagnetic to scalar wavesThese technologies have now shifted from electromagnetic wave to scalar waves and use super quantum computers in the quantum cloud to control a€?pipesa€? a reference to the brains of humans that have been taken over via DNA, via implants that can be breathed can breach the blood-brain barrier and then controlled via scalar waved on a super-grid. Eventually, such 'subvocal speech' systems could be used in spacesuits, in noisy places like airport towers to capture air-traffic controller commands, or even in traditional voice-recognition programs to increase accuracy, according to NASA scientists."What is analyzed is silent, or sub auditory, speech, such as when a person silently reads or talks to himself," said Chuck Jorgensen, a scientist whose team is developing silent, subvocal speech recognition at NASA Ames Research Center in California's Silicon Valley.
We numbered the columns and rows, and we could identify each letter with a pair of single-digit numbers," Jorgensen said. People in noisy conditions could use the system when privacy is needed, such as during telephone conversations on buses or trains, according to scientists."An expanded muscle-control system could help injured astronauts control machines. If an astronaut is suffering from muscle weakness due to a long stint in microgravity, the astronaut could send signals to software that would assist with landings on Mars or the Earth, for example," Jorgensen explained. These are processed to remove noise, and then we process them to see useful parts of the signals to show one word from another," Jorgensen said.After the signals are amplified, computer software 'reads' the signals to recognize each word and sound. Our Research and Development Division has been in contact with the Federal Bureau of Prisons, the California Department of Corrections, the Texas Department of Public Safety, and the Massachusetts Department of Correction to run limited trials of the 2020 neural chip implant.


We have established representatives of our interests in both management and institutional level positions within these departments. Federal regulations do not yet permit testing of implants on prisoners, but we have entered nto contractual agreements with privatized health care professionals and specified correctional personnel to do limited testing of our products.
We need, however, to expand our testing to research how effective the 2020 neural chip implant performs in those identified as the most aggressive in our society.
In California, several prisoners were identified as members of the security threat group, EME, or Mexican Mafia.
They were brought to the health services unit at Pelican Bay and tranquilized with advanced sedatives developed by our Cambridge,Massachussetts laboratories. The results of implants on 8 prisoners yielded the following results: a€?Implants served as surveillance monitoring device for threat group activity. However, during that period substantial data was gathered by our research and development team which suggests that the implants exceed expected results. One of the major concerns of Security and the R & D team was that the test subject would discover the chemial imbalance during the initial adjustment period and the test would have to be scurbbed.
However, due to advanced technological developments in the sedatives administered, the 48 hour adjustment period can be attributed t prescription medication given to the test subjects after the implant procedure.
One of the concerns raised by R & D was the cause of the bleeding and how to eliminate that problem.
Unexplained bleeding might cause the subject to inquire further about his "routine" visit to the infirmary or health care facility. Security officials now know several strategies employed by the EME that facilitate the transmission of illegal drugs and weapons into their correctional facilities. One intelligence officier remarked that while they cannot use the informaiton that have in a court of law that they now know who to watch and what outside "connections" they have. The prison at Soledad is now considering transferring three subjects to Vacaville wher we have ongoing implant reserach. Our technicians have promised that they can do three 2020 neural chip implants in less than an hour. Soledad officials hope to collect information from the trio to bring a 14 month investigation into drug trafficking by correctional officers to a close. Essentially, the implants make the unsuspecting prisoner a walking-talking recorder of every event he comes into contact with. There are only five intelligence officers and the Commisoner of Corrections who actually know the full scope of the implant testing. In Massachusetts, the Department of Corrections has already entered into high level discussion about releasing certain offenders to the community with the 2020 neural chip implants.
Our people are not altogether against the idea, however, attorneys for Intelli-Connection have advised against implant technology outside strick control settings. While we have a strong lobby in the Congress and various state legislatures favoring our product, we must proceed with the utmost caution on uncontrolled use of the 2020 neural chip.
If the chip were discovered in use not authorized by law and the procedure traced to us we could not endure for long the resulting publicity and liability payments. Massachusetts officials have developed an intelligence branch from their Fugitive Task Force Squad that would do limited test runs under tight controls with the pre-release subjects. Correctons officials have dubbed these poetnetial test subjects "the insurance group." (the name derives from the concept that the 2020 implant insures compliance with the law and allows officials to detect misconduct or violations without question) A retired police detective from Charlestown, Massachusetts, now with the intelligence unit has asked us to consider using the 2020 neural chip on hard core felons suspected of bank and armored car robbery. He stated, "Charlestown would never be the same, we'd finally know what was happening before they knew what was happening." We will continue to explore community uses of the 2020 chip, but our company rep will be attached to all law enforcement operations with an extraction crrew that can be on-site in 2 hours from anywhere at anytime. We have an Intelli-Connection discussion group who is meeting with the Director of Security at Florence, Colorado's federal super maximum security unit. The initial discussions with the Director have been promising and we hope to have an R & D unit at this important facilitly within the next six months. Napolitano insisted that the department was not planning on engaging in any form of ideological profiling. I will tell him face-to-face that we honor veterans at DHS and employ thousands across the department, up to and including the Deputy Secretary," Ms. Steve Buyer of Indiana, the ranking Republican on the House Committee on Veterans' Affairs, called it "inconceivable" that the Obama administration would categorize veterans as a potential threat.
