Question

6 for an enzyme to be able to catalyze a reaction, the active site must - a be occupied by an inhibitor b increase the activation energy level c have a complementary shape to the substrate d cause the enzyme to be destroyed in the reaction

Explanation:

Enzymes work based on the lock - and - key model. The active site of an enzyme must have a complementary shape to the substrate to form an enzyme - substrate complex and catalyze the reaction. An inhibitor binding to the active site would prevent the reaction. Enzymes lower activation energy, not increase it. Also, enzymes are not destroyed in the reaction they catalyze.

Answer:

C. have a complementary shape to the substrate
