Quizplus · Accepted Answer

The active site of an enzyme is the part where the substrate molecules fit and has a particular and specific shape. These two characteristics make it possible for the enzyme to catalyze a specific reaction. The shape of the active site is determined by the amino acid sequence of the protein that makes up the enzyme, and it does not change when other reactions are needed.
