WebNov 1, 2014 · The closer the pH is to 7, the higher the reaction rate. As the pH distances from the optimum, however, the reaction rate decreases because the shape of the enzyme's active site begins to deform, until it becomes denatured and the substrate can no longer fit the active site. Enzymes Watch on Answer link WebpH is a major factor affecting the activity of enzymes. The ionization of amino acid molecules and atoms occurs when the pH is altered, thereby affecting the structure and form of proteins and hence disrupting their activities. The velocity of the enzyme is highest in the presence of its optimum pH, below and above which the velocity is much lower.

WebMar 4, 2024 · The pH of a solution can impact the enzyme because enzymes are composed of amino acid chains that have functional groups. These functional groups are vulnerable to changes brought on by surrounding charges. Temperature affects enzymes by increasing the bond energy, causing the atoms in the enzyme's bonds to drift apart from each other. …
