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: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction.

Detailed explanation-3: -Difference between enzyme and catalyst Enzymes are proteins that increase rate of chemical reactions converting substrate into product. Catalysts are substances that increase or decrease the rate of a chemical reaction but remain unchanged.

Detailed explanation-4: -Enzyme Catalysis. Enzyme catalysis is a procedure to increase the rate of virtually all the chemical reactions within cells by the active site of a protein. Enzyme may be part of a multi-subunit complex. It may also transiently or permanently conjugate with a cofactor.

Detailed explanation-5: -This is where the reactant or substrate for a particular chemical reaction combine to the enzyme. We often refer to enzymes as biological catalysts because they catalyze chemical reactions that take place inside the body. A good example of a chemical reaction that’s catalyzed by enzymes would be cellular respiration.
