Enzymes Essay Introduction Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food, for stimulating the brain, for providing cellular energy, and for repairing all tissues, organs, and cells. There are three types of enzymes: metabolic enzymes, digestive enzymes, and food enzymes. Metabolic enzymes catalyse, or spark, the reactions within the cells. The body's organs, tissues and cells are run by metabolic enzymes. Without …showed first 75 words of 785 total…

Heat can also affect the rate as heat gives the enzyme particles more energy as this can effect the rate at which enzymes work, most enzymes will work most efficiently at around 41°c however at greater temperatures the rate at which the enzymes will slow and eventually stop completely, this is because the enzymes denature.
