Correct Answer
B. Catalyze specific chemical reactionsExplanation
Enzymes are proteins that act as catalysts in biological reactions. They speed up the rate of chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes are highly specific, meaning that each enzyme catalyzes a particular chemical reaction. They do not form genes, carry out protein synthesis, or build cell structures. Instead, enzymes play a crucial role in catalyzing specific chemical reactions in cells.Rate this question:
