Which of the following is true concerning the rate-limiting step in a metabolic pathway?

Question

Quizplus · Accepted Answer

The rate-limiting step in a metabolic pathway is usually the slowest reaction in the pathway, as it sets the overall rate of the pathway. Additionally, it may be subject to end-product inhibition, where the final product of the pathway inhibits the rate-limiting enzyme to regulate the pathway's flux. Therefore, both options A and C are correct, leading to answer choice D. Answer choices B and E are incorrect, as the rate-limiting step cannot be the fastest reaction in the pathway.
