Document Summary

Summary: c6h12o6+6o2 6co2+38 atp, glycolysis 2(nadh) * 3 = 6 atp. Net atp of 2: krebs cycle 8(nadh)*3=24 atp. 2(fadh2)*2=4 atp: net atp gtp 2 atp, total: 38 atp! Aerobic metabolism: respiration: krebs cycle: metabolizes two-carbon units called acetyl groups to co2 and h2o, doorways into krebs cycle: pyruvate loses a molecule of co2 and oxidized by. Nad, resulting two carbon acetyl group is attached to coenzyme a, forming. Produces 4 co2, 6nadh, 2 fadh2, 2 atp. Overall: 4 atp, all glucose e is stored in nadh and fadh2 to be used in etc. O2, begins during one of the energy releasing dehydrogenation reactions of catabolism. 2 h atoms are transferred to nad, forming reduced nad. Accept e- from e- donor, transfer to e- accept. Conserving for atp synthesis some of the energy released during. Higher you enter waterfall etc more energy you let out.

The complete conversion of a molecule glucose to six molecules of carbon dioxide via glycolysis and the Krebs cycle requires 19 reactions. Put the reactions that are given below in the proper order, beginning with the phosphorylation of glucose to form glucose-6-phosphate and ending with the oxidation of malate to form oxaloacetic acid.

1) 1,3-bisphosphoglycerate + ADP --> 3-phosphoglycerate + ATP
2) fumarate + H₂O --> malate
3) isocitrate + NAD⁺ --> alpha-ketoglutarate + NADH + H⁺ + CO₂
4) phosphoenol pyruvate + ADP --> pyruvate + ATP
5) Succinyl-CoA + GDP + P_i --> succinate + GTP + CoASH
6) glyceraldehyde 3-phosphate + NAD⁺ + P_i --> 1,3-bisphosphoglycerate + NADH + H⁺

Thank you for the help!
