the activity of an enzyme can be affected by the change in condition the temperature and concentration of substrate explain this with suitable graphical representation for 5 marks
Enzymes are sensitive to environmental circumstances. It could be influenced by temperature, pH, substrate concentration and enzyme concentration. The rate of enzyme reaction is tallied by the amount of substrate changed or the amount of product formed, during a period. Temperature: Heating increases molecular motion. Thus the molecules of the substrate and enzyme move more quickly resulting in a tremendous probability of occurrence of the reaction. The temperature that stimulates maximum activity is referred to as optimum temperature.
pH=The optimum pH is that at which the maximum rate of reaction occurs. Thus the pH modification leads to an alteration of enzyme shape, including the active site. If apexes of pH are experienced by an enzyme, then it will be denatured.
