. B.9(C) For an enzyme to be able to catalyze a reaction, the active site must---- *
1 point
be occupied by an inhibitor

Answers

A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.

The correct answer is:

Option C. have a complementary shape to the substrate.

This can be explained as:

If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.

Activation energy is the minimum amount of energy needed for the reaction.

If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.

Therefore, the active site should have a complementary shape to the substrate.
