What is the energy of activation? 16. How do enzymes speed the rate of reaction? 17. Talk about the effect of the following on enzyme reaction rate: a) Substrate concentration b) pH c) Temperature 18. How do vitamins play a part in enzymatic reactions?
The rate of enzymatic reaction, as for any chemical reaction, depends on temperature. However, the rate abruptly drops above certain temperature, which is different for different enzymes. How would you explain this phenomenon?

Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
1 Consider this graph that we talked discussed in class on how an enzymes affects the rate of product formation. Catalyzed Uncatalyzed reaction Substrate concentration Now consider you have discovered an allosteric inhibitor of the enzyme. You do this experiment again, adding enough allosteric inhibitor to block 50% of the enzyme activity present in the reaction. a. Thinking in terms of the models shown in class, what does it actually mean in molecular terms when "50% of the enzymatic activity"...
Describe the catalytic cycle of an enzymatic reaction. Draw a diagram and explain.

3. "Enzymes affect reaction rates, not equilibria." This is a fundamental concept of enzyme action. Explain, in your own words, why enzymes cannot alter the equilibrium of a reaction. Then explain how enzymes can actually speed up a reaction. 4. How is the activation energy AG different from the biochemical standard free energy change AG"? 5. Explain why AG's p can be different from AG p.s. Describe the implication of this difference in terms of the direction of the reaction...
How do enzymes catalyze reactions? A) Enzymes bind with and change the conformation of substrates. B) Enzymes change the free energy of the reactants. C) Enzymes increase the activation energy of a reaction. D) Enzymes carry out a reaction without needing reactants. E) Enzymes are denatured by a reaction to catalyze it.
In enzymes, what happens to the rate of reaction as the temperature increases? Explain in terms of how molecules collide and product conversion rates. What happens to the enzyme activity if you infinitely increase the temperature?
