Document Summary

Friday, o(cid:272)to(cid:271)er (cid:1006)(cid:1004), (cid:1006)(cid:1004)(cid:1005)(cid:1011) (cid:1012):(cid:1005)(cid:1005) am: energy yield from glycolysis, glucose > 6 co2 = -686 kcal/mole, 2 atps produced = 2x7. 3 = 14. 6 14. 6 kcal/mole. Energy yield 14. 6/686 = 0. 0213 2% recovered as atp (low efficiency) Subsequent oxidation of pyruvate and nadh can recover more of the free energy from glucose: quiz question, answer: b, quiz question. Answer: a b/c 2 out of 2 is 100% Glycolysis produces 2 atp per glucose molecule: pyruvate & glycolysis, 3-c sugar, still contains a lot of energy, 1 molecule of glucose > 2 molecules pyruvate, all cells use glycolysis, need to regenerate nad+ https://onedrive. live. com/view. aspx?resid=c5310d6a66e98d52!121&app=onenote&authkey=!apqq1udavatjxly. Onenote online: at end of glycolysis the pathway diverges : most effective is aerobic respiration. Preparing pyruvate for citric acid cycle/ tca/ krebs cycle. Nad + is reduced into nadh: 1 nadh produced per pyruvate. Finally transfer rest of pyruvate into coenzyme a. So acetyl co a goes into the citric acid cycle.
