Enzymes

Enzymes are often described as the biological catalysts that make life possible. They accelerate thousands of chemical reactions inside cells, but simply having an enzyme present is not enough. Cells must also control when an enzyme works, where it works, and how strongly it works. If metabolic enzymes remained active all the time, cells could […]

Introduction Enzymes are biological catalysts that make the chemical reactions of living organisms possible at useful rates. Almost every major biochemical process depends on enzymes, including digestion, cellular respiration, energy production, DNA synthesis, metabolism and the formation of biological molecules. Without enzyme catalysis, many biochemical reactions would occur too slowly to support life. Enzymes accelerate
