The citric acid cycle is a stage of catabolism that oxidizes acetate into carbon dioxide and generates energy. There are eight enzymes involved in the citric acid cycle.

Which enzymes produce coenzyme A as a product?

A. citrate synthase
B. succinic dehydrogenase
C. succinyl‑CoA synthetase
D. fumarase

The correct answer is option A. "citrate synthase" and C. "succinyl‑CoA synthetase".

Explanation:

Citrate synthase is the enzyme that catalyzes the first reaction of the citric acid cycle, which is the the conversion of oxaloacetate and acetyl-coenzyme A into citrate and coenzyme A. Succinyl‑CoA synthetase catalyzes the reversible reaction of succinyl-CoA to succinate, letting coenzyme A as byproduct of the reaction.Therefore, these two enzymes produce coenzyme A as a product of their reactions.

Explanation:

The citric acid cycle (CAC) which is also called the tricarboxylic acid cycle (TCA) but this was originally referred to as the Krebs cycle. This is an important in respiration that is designed to carefully release energy from acetyl-CoA in a series of chemical reactions by using eight different enzymes.
