The citric acid cycle is a series of oxidation reactions that removes carbon atoms from substrates in the form of CO2
Once a molecule of acetyl CoA enters the citric acid cycle, how many complete cycles are required for both of the carbon atoms in its acetyl groupto be oxidized to CO2?
(a) 1
(b) 2
(c) 3
(d) 4
(d) The carbons from acetyl CoA are carried through the entire first reaction cycle. In the second cycle, one of these carbons is oxidized to CO2. Two more cycles later, the second carbon molecule from that same acetyl CoA is oxidized to CO2.
