27. Which statement about the transition state of an enzyme-catalyzed reaction is true?
(A) The transition state is identical to the enzyme-substrate complex.
(B) The transition state always has a lower free energy than the substrate.
(C) Enzymes form a lower-energy transition state complex, reducing activation energy.
(D) The transition state cannot be bound by an enzyme due to its instability.
(E) Enzymes stabilize the substrate more than the transition state.
