Explanation:
Detailed explanation-1: -The correct answer is A. Enzymes lower the activation energy of a reaction. Enzymes are biological catalysts that are known to lower the activation energy of reactions to allow the reaction rate to increase.
Detailed explanation-2: -The answer is A. Enzymes increase the rate of chemical reaction by lowering activation energy barriers.
Detailed explanation-3: -Answer and Explanation: Enzymes are proteins that speed up chemical reactions.
Detailed explanation-4: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.
