THE RATE OF REACTION OF SUCCINATE DEHYDROGENASE Introduction: Enzymes are protein molecules that function as biological catalysts that can help break larger molecules into smaller molecules while remaining unchanged themselves. They speed up the chemical reactions by lowering the energy of activation barrier, are specific to one molecule. The enzyme's specificity arises from its active site, an area with a shape corresponding to the molecule with which it reacts (the substrate). The shape of the enzyme where the chemical binds only allows the binding of that particular chemical, or inhibitor substrates that are structually similar to the substrate, competing for the active site. The enzyme and the substrate slot together (like a key for a lock, or by induced fit) forming an enzyme-substrate complex that allows the reaction to take place. An enzymes activity is affected by its environment. Each enzyme has a temperature and pH level at which its activity is...
