I mean yeah everybody can tell you if you don't eat, you don't have the energy or building materials you need to make your body. But stop to think about that for a moment. If I need to grow some hair, unless I go down to a barber shop and start snacking off of the floor, how the heck does the food I eat become human hair? Ap biology essay enzymes that matter, ap biology essay enzymes, how does sugar become energy? Well, it turns out all these processes are helped along by the special molecules called enzymes.
Or those helper molecules called co-enzymes or cofactors that help enzymes do their job. On the other hand I use this pair of scissors and give it a little snip, easy. Now were the scissors used up in doing this?
I can keep doing it over and over again and again and same thing with enzymes. With that same pair of scissors work however, if a co-enzyme provided me a tree branch, nope. Why not?
On the other hand, if I had a chain saw, it goes through easily, ap biology essay enzymes. Enzymes are proteins catalysts. Now what does that mean? Protein catalysts are enzymes that can put together or tear apart other molecules, without being used up in the process.
So a catalyst, what it does is, it lowers the activation energy required ap biology essay enzymes a chemical reaction ap biology essay enzymes occur. Now, the part of the enzyme that actually fits to the substrate, ap biology essay enzymes, is called the active side.
If we take a look at this, you can see here this is the active site of the enzyme and this is the substrate, ap biology essay enzymes, the molecule that is going to be working on. Notice the precise match up to this. The new model now is called the Induced Fit model. If we take a look at that, you can see the active site is close to the right shape and not quite as the enzyme gets closer and closer, it starts ap biology essay enzymes cause the active site to change shape, until it precisely fits, ap biology essay enzymes.
But this causes a strain on the enzyme which alternately causes a strain on the substrate. It helps it break things apart. If you want a model for that, think of a stapler. Now what is it again that allows us to work? Now can I cut with any part of the enzyme? I have to put my fingers right here in the active site. Now what is it that gives it that precise shape? If we take a look at this protein here and you watch it rotate, these precise shapes here are what give it that three dimensional shape.
If you want to ap biology essay enzymes another point, what cause the tertiary structure? It's the interactions between the different parts of the enzymes. With the R-groups of each amino acid forming hydrogen bonds. On the AP test, they love to ask questions about the AP lab number six.
Now in a enzyme lab, what they do is they fool around with the pH, the temperature and the concentration of substrate involved around an enzyme.
Then they look to see how does that affect the rate of how that enzyme can work. If we start fooling around with the pH and you should know that pH is the concentration of hydrogen ions in the solution, we start changing the number of hydrogen ions that are around that enzyme. So if I was talking about an enzyme in a bloodstream which usually has a pH around 7. So it stops working so well. When you get outside, too far out, it stops working entirely. So they would be natured if though they wound up in your blood.
Now what about temperature? When you get past its optimal temperature, eventually you get so much heat energy that those R groups are no longer able to hold on to each other, because those ap biology essay enzymes bonds.
Remember that. Those hydrogen bonds get overwhelmed. There is that point. Now what is this orange one? That represents an enzyme perhaps from some kind of bacteria that lives in hot volcanic pools. So it will have an optimal pH at much higher temperature. Now, before I go into how things respond to change in their substrate concentration, I want to give you a model that you know of, that will demonstrate responses to pH and temperature, ap biology essay enzymes.
What color is it when it comes out of the egg? What is that? Albumin is the name of the protein that makes up egg white. Albumin is actually this long chain that gets wound up into a tight little ball. Now if I take a model of albumin say this. This looks normal, ap biology essay enzymes.
If I start to heat it up though, it starts to unwind. What was keeping it in the shape here? Just like if you cook the clear albumin, that ball unwinds and starts to form a thick tangled mat that becomes a solid, instead of being ap biology essay enzymes little balls that can roll all over your hands.
The same thing with pH. If I alter the pH, it unwinds. Obviously, the more substrate you give to ap biology essay enzymes enzyme, the more it can do its reaction. But eventually you get to a point where you level off on this. Just like if I go back into my scissor model. If somebody hands me one piece of paper per minute, I can do one paper torn in half per minute. Those are things called cofactors and co-enzymes. These are essentially helper molecules that help the enzyme do its job.
Now a number of these cofactors fall under the category of what are called negative regulators. That means that they slow down the enzyme. They stop it from doing its doing. Now some of them are competitive inhibitors.
Notice this little red, guy lands in the active site and blocks it. On the other hand you can have the inhibitor land on a different site. Notice this allosteric site. If the inhibitor molecule comes into there, it changes the shape of the substrate, ap biology essay enzymes. You should know that allosteric sites, allo- means other or separate. So this allosteric site, when the inhibitor molecule lands on it, gives the enzyme an alternate shape that no longer fits. Now there can be positive regulators or activators.
These might be things that help it open up. Magnesium ions are a common cofactor that are positive regulators for many enzymes. ATP is an example of a coenzyme. I could be that. I provide the energy for my enzyme. There you go. You now know everything you need to know about enzymes to do well in the AP Biology exam, ap biology essay enzymes. You also know that there are helper molecules called coenzymes ap biology essay enzymes cofactors.
They help enzymes do their job, ap biology essay enzymes. Look for the one that ends in —ase. Guess what?
