Question

which of the following statements best explains why enzymes are specific to the reactions they catalyze? enzymes are always the same shape. enzymes are made of sugars. the shape of the enzyme matches only certain molecules. enzymes are not proteins.

Enzymes are highly specific in the reactions they catalyze due to their unique three - dimensional shapes. The active site of an enzyme has a shape that is complementary to the shape of its specific substrate (certain molecules). This is like a lock - and - key mechanism.

Answer:

The shape of the enzyme matches only certain molecules
