How does the shape of an enzyme affect its function? a. the shape holds molecules that provide more energy to the reaction. b. the shape is matched to the reactants, holding them in place and lowering the activation energy. c. the shape the enzyme synthesize extra reactants for the reaction. d. the shape lower the δh of the reaction.

B. The shape is matched to the reactants, holding them in place and lowering the activation energy.

Explanation:

Hello,

In biochemistry, enzymes are widely known as catalysts which allow biochemical reactions to be either carried out or fastened, in such a way their working principle lies on the dovetailing of the substrate into the enzyme's so called "actives sites" (attached figure) wherein the substrate is allowed to undergo the desired chemical reaction, thus, the activation energy is diminished so the chemical reaction becomes possible.

Best regards.
