Enzymatic Nature of Metabolic Reactions
Self-Assessment Questions and Tasks

1. What is The Nature of Enzymes?

2. Describe The Structure of an enzyme and each of its functional centers.

3. Explain The sequence of interactions between the substrate and the enzyme.

4. How does the reaction rate depend on the concentration of the enzyme and the substrate? Why does increasing the Substrate Concentration cause the reaction rate to increase up to a certain point, after which it remains constant?

How does the reaction rate vary with Temperature? What is the optimal temperature and why?

How does enzyme activity depend on the pH of the medium? Why do enzymes generally function in near-neutral environments rather than in strongly acidic or alkaline media?

How do inhibitors affect enzyme activity? Describe the MECHANISM OF ACTION for each type of inhibition. What distinguishes them from one another?

With which type of inhibitor does activator binding occur? Can activators bind to other sites on the enzyme? Why?

Some enzymes are active only in the presence of Vitamins. Why? In which part of the enzyme do vitamins function?
