Which of the following is NOT true of enzyme activity? a. enzyme shape may change during catalysis b. the active site on an enzyme orients its substrate molecules, therby promoting interaction of their reactive parts c. all enzymes have an active site where substrates are temporarily bound d. each enzyme can catalyze a wide variety of different reactions

D. Each enzyme can catalyze a wide variety of different reactions

Explanation:

Each enzyme can only catalyze a few, specific types of reactions.

Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.

If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.

So, each enzyme can only assist in a few reactions.

The correct answer is D. Each enzyme can catalyze a wide variety of different reactions
