Understanding Enzyme Activity

Enzymes are biological catalysts that speed up chemical reactions in the body. They lower the activation energy required for reactions to occur, enabling processes such as digestion, metabolism, and DNA replication. Each enzyme has a specific structure that is crucial for its function, and the active site of an enzyme is the region where substrate molecules bind. Understanding how enzymes work is essential for comprehending broader biological processes.
