Answer:

The correct answer is B  An enzyme binds to the substrate at enzyme"s substrate site.

Explanation:

Enzyme is proteinecious in nature and act as homogenous biological catalyst.Enzyme contain an active site or substrate binding site to which specific substrate binds.

         The active site of an enzyme contain many amino acids such as cystein,histidine,aspartic acid ,glutamic acid.These amino acids contain functional groups  such as -SH group,-OH group,-COOH group. These functional group facilitate the binding of substrate to the active site of an zymes.
