In cells,the activity of enzymes is often regulated by other molecules.Why is this necessary?
A)because all enzymes require some help from another molecule to function correctly
B)because other molecules are necessary to prevent enzymes from denaturing
C)because each enzyme has multiple functions
D)because it is unlikely that all reaction products are required all of the time

Question

Quizplus · Accepted Answer

Enzymes catalyze specific reactions, and their activity must be regulated to ensure that the right amount of product is produced at the right time. If the product is not required, the enzyme may need to be inhibited, and if more of the product is needed, the enzyme needs to be activated. Therefore, the activity of enzymes is often regulated by other molecules to ensure that the right amount of product is produced at the right time.
