Maintaining a Balance 1. Most organism are active in a limited temperature range The role of Enzymes in metabolism‚ their chemical composition and specificity on substrates Role of enzymes * Enzymes are organic catalysts. They are protein molecules that increase the rate of the reactions in living organisms. * Without enzymes‚ metabolic reactions at body temperatures would be too slow to produce sufficient energy to maintain life * Intracellular enzymes are used in the cells
