MEDICAL PHYSIOLOGY

Detailed explanation-1: -These molecules are called coenzymes because they work together with enzymes to enhance reaction rates. In contrast to substrates, coenzymes are not irreversibly altered by the reactions in which they are involved.

Detailed explanation-2: -The macromolecule that functions in the selective acceleration of a chemical reaction is a protein known as an enzyme. An enzyme is a biological catalyst, a catalyst lowers the activation energy of a chemical reaction allowing it to proceed at a faster rate with a lower input of energy.

Detailed explanation-3: -a macromolecule serving as a catalyst a chemical agent that increases the rate of a reaction without being consumed by the reaction. Most enzymes are proteins. a series of chemical reactions that either builds a complex molecule or breaks down a complex molecule to simpler molecules.

Detailed explanation-4: -An enzyme is a protein that acts as a catalyst in biochemical reactions. Substrates bind to its active site and are turned into product.

Detailed explanation-5: -Answer and Explanation: The molecule that the catalyst/enzyme acts on is called the substrate. The substrate will bind the enzyme on its active site. The enzyme will then lower the activation energy of the reaction, allowing it to proceed until the final product is formed by the enzyme.
