in step 5 of the citric acid cycle, the energy released when _______ is released from succinyl coa is used to produce gtp and then atp.

succinate
inorganic phosphate
coenzyme a
electrons

Explanation:

In step 5 of the citric acid cycle, succinyl - CoA is converted to succinate. During this reaction, Coenzyme A (CoA) is released from succinyl - CoA. The energy released from this release is used to produce GTP (which can then be used to produce ATP). Succinate is the product, not the substance released. Inorganic phosphate is involved in the phosphorylation but not the substance released from succinyl - CoA. Electrons are not released in this step in the context of producing GTP/ATP from succinyl - CoA. So the correct substance is Coenzyme A.

Answer:

Coenzyme A
