FORMS AT THE END OF GLYCOLYSISWhich of these is NOT true of the citric acid cycle? O The citric acid cycle occurs in the mitochondria. The citric acid cycle produces ATP via oxidative phosphorylation. The citric acid cycle produces two ATP per glucose molecule. The citric acid cycle uses both NAD+ and FADH as electron carriers.myristic acid (14:0) to carbon dioxide and watera. rounds of the beta oxidation pathway will be involvedb. how many moles of acetyl CoA will be produced after complete beta oxidationc. how many moles of ATP will be obtained after complete beta oxidation
- A high concentration of which of the following would activate the citric acid cycle?

Carbon dioxide is released when alpha-ketoglutarate is transformed to Succinyl CoA.Which of the following is the third step of Citric Acid Cycle? Select one: a. Succinyl-CoA becomes Succinate and forms one ATP molecule and Coenzyme A-SH b. Pyruvate is decarboxylated to become acetyl-CoA producing NADH and Carbon dioxide c. Isocitrate and then decarboxylated and oxidized to produce alpha-ketoglutarate, Carbon dioxide and NADH d. alpha-ketoglutarate is oxidized and decarboxylated to produce Succinyl-CoA, Carbon dioxide and NADH e.
