During the citric acid cycle: choose the correct answer from the following choices, and then select the submit answer button. atp is synthesized by substrate-level phosphorylation. fuel molecules are completely reduced. high-energy electrons are removed from nad+ and fadh. atp is synthesized by oxidative phosphorylation.

The correct answer will be option-ATP is synthesized by substrate-level phosphorylation.

Explanation:

Citric acid cycle or the Krebs cycle is the series of chemical change taking place during the cellular respiration which releases stored energy through the oxidation of acetyl-CoA.

During the Citric acid cycle, 2 ATP, 6 NADH and 2 FADH₂ are released by two acetyl CoA oxidation. The production of ATP takes place during the conversion of Succinyl CoA to succinate where the released energy is used to form GTP which then converts to ATP.  

Thus, ATP is synthesized by substrate-level phosphorylation is the correct answer.
