what is a substrate?\n a molecule that acts as a catalyst\n a place on the enzyme where the reaction occurs\n a place on the product where the enzyme fits\n a reactant that is catalyzed by an enzyme

Answer

Brief Explanations:

In biochemistry, a substrate is a reactant molecule upon which an enzyme acts to catalyze a chemical - reaction. A molecule that acts as a catalyst is an enzyme. The place on the enzyme where the reaction occurs is the active - site. There is no such thing as a place on the product where the enzyme fits in the context of substrate - enzyme interaction.

Answer:

a reactant that is catalyzed by an enzyme
