Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one
