Question

Which statement best describes the mechanism by which enzymes catalyze a reaction? A. Enzymes absorb the change in enthalpy (ΔH), permitting a reaction to proceed. B. Enzymes lower the concentration of the substrates, thereby driving the equilibrium to favor product formation. C. Enzymes are completely used up in the course of the reaction and therefore favor product formation. D. Enzymes lower the energy barrier necessary to achieve the transition state of a reaction. E. Enzymes lower the concentration of the products, thereby driving the reaction to favor product formation.

Answer 1

Answer:

Option E,  Enzymes lower the energy barrier necessary to achieve the transition state of a reaction.

Explanation:

Enzymes  just act like bio catalyst to favor the formation of final product at a given physical and chemical condition. Thus these enzymes reduces the energy required for reaching the transition stage through a process called catalysis.  Enzymes do not modify or change the final products however they enhance the rate of biochemical reaction.

Thus, option E is correct
