Enzymes do not change which of the following?
Correct answer: D. Options A, B and C are correct
- A. Concentration of products
- B. Concentration of reactants
- C. Keq
- D. Options A, B and C are correct
Explanation
Keq is called the equilibrium constant which is the ratio of the concentration of products to the concentration of reactants. Keq does not change as it serves as a constant and relates the specific concentrations of all reactants and products at equilibrium at a given temperature and pressure.Enzymes do not alter the concentration of reactants. They do not consume or change the amount of reactants present in a reaction.In conclusion: Enzymes do not change the concentration of reactants, the concentration of products, or the equilibrium constant (Keq) of a chemical reaction. Their role is to increase the rate at which equilibrium is achieved without affecting the final composition of the reaction mixture at equilibrium. The correct answer is: D. All Options A B and C are correct.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
