Question

Quizplus · Accepted Answer

The substance acted on by an enzyme is called a substrate. The enzyme binds to the substrate and helps to speed up the reaction. A catalyst is a substance that speeds up a chemical reaction, but it does not specifically refer to the substance acted on by an enzyme. An apoenzyme is the protein part of an enzyme, and a coenzyme is a non-protein organic molecule that helps enzyme activity but is not the substance acted on by the enzyme.
