When the enzyme, Pectinase is at its optimum pH the rate of reaction will be at its maximum compared to when it is not at its optimum pH. Introduction to Enzymes Enzymes are biological catalysts which means that they speed up the chemical reactions that occur in living things. Without the presence of enzymes the time it took to break down molecules would be much longer. A catalyst is any substance which makes a chemical reaction go faster, without itself being changed and it can be used over and over again and not get used up. Enzymes are the same except that they can get denatured by heat and pH, denaturing is not reversible so the enzyme can no longer be used. Enzymes all have an optimum temperature and pH. In the human body the optimum...
