Detailed explanation-1: -Answer: Option C. Explanation: Enzymes are defined as the macromolecular that act as biological catalysts which helps to accelerate chemical reactions. Enzymes increases the rate of chemical reaction by lowering its activation energy.
Detailed explanation-2: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.
Detailed explanation-3: -Answer and Explanation: Enzymes are proteins that speed up chemical reactions.
Detailed explanation-4: -Several factors affect the rate at which enzymatic reactions proceed-temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.
Detailed explanation-5: -According to the most widely accepted theory, enzymes bind to the substrate molecule and form a transition state.
