Enzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).nzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).
So enzymes speed up chemical reactions necessary for use in the body. As such they are a catalyst, meaning they speed up a reaction but are not used up in the process, i.e., the enzyme performs its function, releases the products, and is still the same enzyme. Catalysts speed up reactions by lowering the energy of activation. In other words, it takes less energy for the reaction to proceed. Unlike chemical catalysts, enzymes can be saturated with substrates, and show hyperbolic kinetics. (probably outside of this context).
