Detailed explanation-1: -Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.

Detailed explanation-2: -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-3: -Answer and Explanation: Of the following regarding enzymes, enzymes being consumed by the reaction they catalyze is incorrect. Enzymes are special in that they’re able to catalyze many different reactions without being consumed or used up by the specific reaction.

Detailed explanation-4: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function. Enzymes do not alter the overall change in free energy for a reaction.

Detailed explanation-5: -Which of the following is FALSE concerning enzymes? Explanation: Enzymes will increase the rate of a chemical reaction, but will not alter the equilibrium of a reaction.
