Question

The active site of an enzyme is complementary to :

A. One type of product molecule

B. All types if product molecules

C. One type of substrate molecule

D. All types if substrate molecule

Answer 1

Option C is correct. The active site of an enzyme is a specific region that is complementary to a specific substrate molecule. This means that the active site has a specific shape that only fits with the shape of a particular substrate molecule. Once the substrate molecule binds to the active site, the enzyme can catalyze the reaction to form the product(s).
