Detailed explanation-1: -Enzymes are biological catalysts. They speed up biochemical reactions. Enzymes are involved in most of the chemical reactions that take place in organisms.

Detailed explanation-2: -Enzymes let chemical reactions in the body happen millions of times faster than without the enzyme.

Detailed explanation-3: -Thus, it can be concluded that enzymes are not the reactants, but enzymes are the catalysts that help to convert the reactants into products. Enzymes increase the rate of conversion of the reactants into products by increasing the rate of reaction.

Detailed explanation-4: -This is because they do not participate in the process itself, but what they do is rather give a lower-activation-energy alternative reaction pathway. The same goes for enzymes. So, the answer is No, enzymes are not used up in a reaction. Enzymes are not used up in reactions.

Detailed explanation-5: -All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds.
