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.
The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart. To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment. Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity.


The more often we see the things around us - even the beautiful and wonderful things - the more they become invisible to us. As long as poverty, injustice and gross inequality persist in our world, none of us can truly rest. However, because it can maintain its body temperature within a narrow range, wombats can remain active over a much wider temperature range. Always remember, you have within you the strength, the patience, and the passion to reach for the stars to change the world.
In a world that changing really quickly, the only strategy that is guaranteed to fail is not taking risks. There is no end to the adventures that we can have if only we seek them with our eyes open. You may not realize it when it happens, but a kick in the teeth may be the best thing in the world for you. That is why we often take for granted the beauty of this world: the flowers, the trees, the birds, the clouds - even those we love. Try adding some bright colors to the picture by including humor, and your picture begins to lighten up. Creation is an ongoing process, and when we create a perfect world where love and compassion are shared by all, suffering will cease. I must trust that the little bit of love that I sow now will bear many fruits, here in this world and the life to come. All she knows is that she wants everything to go back to normal. But when Noah Hutchins, the smoking-hot, girl-using loner in the black leather jacket, explodes into her life with his tough attitude and surprising understanding, Echo's world shifts in ways she could never have imagined. And with the secrets they both keep, being together is pretty much impossible.Yet the crazy attraction between them refuses to go away.
And Echo has to ask herself just how far they can push the limits and what she'll risk for the one guy who might teach her how to love again..
