How do enzymes catalyse chemical reactions
WebApr 9, 2024 · Enzymes are chemical catalysts that accelerate chemical reactions at physiological temperatures by lowering their activation energy. Enzymes are usually proteins consisting of one or more polypeptide chains. Enzymes have an active site that provides a unique chemical environment, made up of certain amino acid R groups (residues). WebThe enzymes that catalyse reactions in each area have an optimum. pH that matches the pH of the area. For example, enzymes that work in the stomach have a very low optimum pH because of the acid ...
