The Citric Acid Cycle Begins With. Reduced electron carriers generated in the cycle are reoxidized by oxygen via the electron transport. Krebs cycle (tca or citric acid cycle):

What breaks the double bond with said oxygen. The citric acid cycle begins by combining multiple choice pyruvate and acetic acid to form acetoacetic acid. Products and functions of the krebs cycle for one cycle, two molecules of carbon, three molecules of nadh, one molecule of fadh2 and one molecule of atp or gtp are produced.
