WebJan 3, 2024 · Enzymes also confer extraordinary specificity to a chemical reaction. 3.3: Enzyme Kinetics Unlike uncatalyzed (but readily occurring) reactions, in which the rate of the reaction is dependent only on the concentration of the reactants, the rate of enzyme-catalyzed reactions is limited by the number of enzyme molecules available. WebSep 9, 2024 · These reactions do not occur randomly, but are controlled by biological catalysts called enzymes. Enzymes accelerate the rate of chemical reactions by lowering the activation energy needed to trigger the reaction. Without enzymes, chemical reactions would not occur fast enough to support life. WebEnzymes also control reactions. If you think about the amount of energy that is release in most chemical reactions, we would likely spontaneously combust anytime anything took place within our body in a spontaneous and uncontrolled manner.
