WebSo, why does pH affect enzyme activity? pH affects enzyme activity because enzymes are proteins that get their molecular structure via interactions between the charges of the amino acids that form the protein chains. These interactions are in the form of a hydrogen bond which is affected by the pH level. WebAnd so because of that, depending on your enzyme and sometimes the substrate that you're dealing with, you might have different reaction velocities at different pHs, with some enzymes doing better in acidic environments and other enzymes doing better in neutral or basic environments.
