However each enzyme has a very specific purpose.
A cofactor is a substance that must be attached to the active site before a substrate can be able to bind and enable the enzyme to work properly. These come in the form of an ion or a molecule. The cofactor of amylase is calcium ions (1,6,) An inhibitor is another molecule (other than a substrate).Essay 1666 Words 7 Pages Introduction Enzymes are macromolecules that act as a catalyst, and it’s a chemical agent that accelerates the reaction without being consumed by the feedback or the results (Campbell and Reece, 2005).
