Concept explainers
(a)
Interpretation:
To identify each component of the given reaction by a represented cartoon figure and assemble them to show the normal enzyme reaction.
Concept Introduction:
Many enzymes contain only protein in their structure. However, some are composed of both protein component and non-protein component. The protein component of an enzyme is called apoenzyme and the non-protein component of an enzyme is called cofactor.
(b)
Interpretation:
To identify each component of the given reaction by a represented cartoon figure and assemble them to show a competitive inhibition.
Concept Introduction:
Competitive inhibition occurs when a substance that is not the substrate of the enzyme under normal condition can also bind to the enzyme’s active site. This results in direct competition with the substrate for the active site.
(c)
Interpretation:
To identify each component of the given reaction by a represented cartoon figure and assemble them to show a noncompetitive inhibition.
Concept Introduction:
Noncompetitive inhibition occurs when an inhibitor binds to a site present on the enzyme that is distinct from the active site which causes an alteration in the shape of the active site, making it unavailable for the substrate.

- The human body has an average pH of about 7 and a temperature of about 37C. Use graphs to illustrate enzyme activity in the human body as a function of the following: a. Substrate concentration b. Enzyme concentration c. pH include pH optimum value d. Temperature include temperature optimum valuearrow_forwardBased on the graphical information in Problem 21-41 about enzymes A and B a. What is the optimum pH for enzyme B? b. What is the optimum temperature for enzyme A? c. Which enzyme has the greater activity at a pH of 7.2? d. Which enzyme has the greater activity at a temperature of 37.2C?arrow_forward. Describe the lock-and-key model for enzymes. Why are the shapes of the enzyme and its substrate important in this model? What does it mean to say that an enzyme is inhibited by a particular molecule? What happens if this inhibition is irreversible? Can you think of a situation in which it might be advantageous to be able to inhibit an enzyme?arrow_forward
