The substance on which the enzyme works;the raw material of the reaction.

Question

Quizplus · Accepted Answer

The substrate is the substance on which the enzyme works, and it is the raw material of the reaction. The other choices are not the substance on which the enzyme acts. The active site is the region of the enzyme where the substrate binds, the coenzyme is a non-protein molecule required for enzyme activity, and the non-catalytic binding site is a region of the enzyme that binds molecules other than the substrate but does not directly participate in the catalytic reaction.
