BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes are also sensitive to pH . Changing the pH of its surroundings will also change the shape of the active site of an enzyme. Many amino acids in an enzyme molecule carry a charge . Within the enzyme molecule, positively and negatively charged amino acids will attract.

Detailed explanation-2: -So, 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.

Detailed explanation-3: -The enzyme ‘s active site binds to the substrate. Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst.
