Webb2 apr. 2024 · Very high temperatures disrupt the shape of the active site, which will reduce its activity by preventing the formation of enzyme/substrate complexes. The enzyme will have been denatured . WebbFor example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. When the pH value deviates from the ideal conditions, the activity of the enzyme slows down and then stops.
