Enzyme activation refers to the process by which enzymes are modified or regulated to increase their catalytic activity. Enzymes are biological molecules that act as catalysts, speeding up chemical reactions within cells. Activation of enzymes can occur through various mechanisms, such as allosteric regulation, covalent modification, or post-translational modifications. By activating enzymes, cells can control the rate of metabolic reactions and maintain homeostasis. Understanding enzyme activation is important in the fields of biochemistry, molecular biology, and drug development.
