WebCatalysts in biology are genetically encoded by the cell, and are called enzymes. Enzymes are made of protein (s), often with non-protein cofactors that are intimately involved in the actual reaction catalyzed (again, cofactors are part of the enzyme and are not "used up" in the reaction). There are some interesting exceptions in which the ... WebHow are enzymes inhibited? There are two types of enzyme inhibition: competitive and non-competitive.
