Enzymes are biological catalysts that facilitate chemical reactions in living organisms. They are typically proteins, although some RNA molecules also have catalytic activity. Enzymes are essential for life because they speed up the reactions that are necessary for cells to function properly. Without enzymes, many biochemical reactions in the body would occur too slowly to support life. Enzymes work by lowering the activation energy required for a chemical reaction to occur. Activation energy is the amount of energy needed to start a reaction, and enzymes reduce this energy barrier, allowing the reaction to occur more quickly. Enzymes do this by binding to specific molecules, called substrates, and positioning them in…
