The Effect of Changing Conditions on Enzyme Catalysis

WebNov 10, 2016 · Most enzymes only function under optimal environmental conditions. If the pH or temperature deviates from these conditions too much, the enzyme reaction slows down significantly or does not work ... WebEach enzyme has an optimal pH. A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule change and the molecule changes shape. The new shape may not be effective. The diagram below shows that pepsin functions best in an acid environment.
