Cells must produce many different enzymes because:

A.enzymes are generally ineffective at speeding up reactions.

B.most cellular reactions require a specific, unique enzyme.

C.enzymes are degraded quickly.

D.rate of production of enzymes is important in regulating energy production by cells.

Solution

Answer:

B.most cellular reactions require a specific, unique enzyme.

Explanation:

The presence of an enzyme allows a reaction to occur, but does not switch outcomes of undergoing reactions. Enzymes do speed up a chemical reactions, the active site on the enzyme may undergo a slight change in shape when the substrate binds, enzymes are very specific in their action, and enzymes lower the energy of activation for a reaction to occur.
