Document Summary
The central role of the tca cycle is: The tca cycle is called an amphibolic cycle because energy is both consumed and produced during the process . General properties= 4 oxidation reactions (what produce the nadh and fadh2), starts off with 6 carbons and loses carbons until it gets to a 4 carbon molecule. Acetyl-coa enters the cycle and nadh, fadh2, co2 and atp come out of the tca cycle. When a glucose or a pyruvate molecule is fully catabolized, all carbons are oxidized to. Co2, in what pathways are they oxidized? (after we learn tca cycle, you should understand this. ) glucose is oxidized to form pyruvate. glucose -> glycolysis pyruvate -> pyruvate oxidation. What are the structures of the molecules involved in each reaction? (all the reactions are important) Step 4: oxidative decarboxylation alpha-ketoglutarate --(nad+)--> succinyl coa. Step 7: hydration of fumarate to form malate.
