Detailed explanation-1: -Enzymes are proteins that act upon substrate molecules and decrease the activation energy necessary for a chemical reaction to occur by stabilizing the transition state. This stabilization speeds up reaction rates and makes them happen at physiologically significant rates.

Detailed explanation-2: -Hormones and enzymes play a vital role in our body by controlling and regulating many functions. Hormones are known as chemical messengers as they trigger many functions, while enzymes are catalysts as they affect the rate of a reaction.

Detailed explanation-3: -Proteins are biopolymeric structures composed of amino acids, of which there are 20 commons found in biological chemistry. Proteins serve as structural support, biochemical catalysts, hormones, enzymes, building blocks, and initiators of cellular death.

Detailed explanation-4: -Proteins have multiple functions, including: acting as enzymes and hormones, maintaining proper fluid and acid-base balance, providing nutrient transport, making antibodies, enabling wound healing and tissue regeneration, and providing energy when carbohydrate and fat intake is inadequate.
