www.inf.ed.ac.uk• The pH optimum for enzyme activity is generally close to the pH of the environment/cell location natural for the enzyme • Pepsin (a) is a stomach enzyme that hydrolyzes peptide bonds allowing the digestion of proteins (e.g. in meat and fish). It has a very acidic optimum of pH 1.6, similar to the stomach environment.

climb.bme.cornell.edureaction between an enzyme and a substrate is complete, the substrate is changed to a product while the enzyme remains unchanged. The rate of the reaction between an enzyme and a substrate can be affected by different factors. Some of the factors that can affect enzyme activity are temperature, pH,
