Slow down or stop the activity of an enzyme

WebbInhibitor are molecules that either slow down or stop the activity of an enzyme. They often bond to the enzyme – causing the shape to change. Remember - When the shape changes, the enzyme will not work the same way. Examples of inhibitors include snake venom and nerve gas from World War I. 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 .

WebbLower temperatures lead to slower chemical reactions. Enzymes will eventually become inactive at freezing temperatures but will restore most of their enzyme activity when temperatures increase again, while some enzymes lose their activity when frozen.

Webb16 aug. 2024 · When the concentration of the enzyme is significantly lower than the concentration of the substrate (as when the number of taxis is far lower than the number of waiting passengers), the rate of an enzyme-catalyzed reaction is directly dependent on the enzyme concentration (part (b) of Figure 18.7. 1 ). 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.
