Document Summary

Nad+ + 2 e- + 2 h+ nadh. The e- removed are delivered to nad+, making nadh. In total, net produced is 2 atp, 2 nadh, & 2 pyruvate per glucose also 2 h2o. Energy investment followed by payoff: 2 atp needed but 4 atp & 2 nadh made. No carbon is lost: 6c glucose = 2 3c pyruvate; but since it"s been oxidized, Iii. potential energy of 2 pyruvate is less than that of 1 glucose. The atp is produced from substrate-level phosphorylation (enzyme-catalyzed reaction that transfers phosphate group from substrate to adp) 6. 4 pyruvate oxidation & citric acid cycle (in mitochondria matrix) E- removed are accepted by nad+ or fad, & substrate-level phosphorylation makes atp. Each acetyl group = 1 cycle = 2 co2, 1 atp, 3 nadh, & 1 fadh2. (note: double the stuff for 1 glucose)
