MCAT Biochemistry Review | Latest Version | 2024/2025 | Graded A+ What is the primary function of the enzyme catalase in cells? Catalase breaks down hydrogen peroxide into water and oxygen, protecting cells from oxidative damage. Explain the role of coenzymes in enzyme-catalyzed reactions. Coenzymes are organic molecules that assist enzymes by providing essential chemical groups or by stabilizing transition states during catalysis. What is the significance of the Km value in en...
