Citric Acid Cycle Steps: ATP Production - ThoughtCo

WebFigure 7.11 In the citric acid cycle, the acetyl group from acetyl CoA is attached to a four-carbon oxaloacetate molecule to form a six-carbon citrate molecule. Through a series of steps, citrate is oxidized, releasing two carbon dioxide molecules for each acetyl group fed into the cycle. In the process, three NAD + molecules are reduced to NADH, one FAD … WebAcetyl \text {CoA} CoA is sometimes called a carrier molecule, and its job here is to carry the acetyl group to the citric acid cycle. The steps above are carried out by a large enzyme complex called the pyruvate dehydrogenase … WebThe Krebs cycle begins as acetyl-CoA (2-carbon molecule) combines with oxaloacetate (4-carbon molecule) to form citrate (6-carbon molecule). Citrate then undergoes transformation into cis-aconitate and then into isocitrate. It is after this step that one of the carbon atoms breaks off and is released as CO2. An NAD+ molecule is also reduced to ... lilybeingsupersilly
