Document Summary

Atp: ribose, nitrogenous base, 3 negative phosphate groups. Krebs cycle and etc take place in matrix of the mitochondria. Glucose - (-2atp) phosphorylated glucose - 2 sugar phosphate (reduced 2 nad into. Glucose is phosphylated so it doesn"t exit the cell, and to make it more reactive. Net gain of 2 atp molecules, pyruvate, doesn"t use oxygen. 3c pyruvate gets converted into acetyl coenzyme a (2c), a carbon was lost through c02 waste product. Krebs cycle: provide atp and reduced nad with releasing c02. Nadh2 and fadh2 are produced by the krebs cycle under aerobic conditions to supply electrons for the etc, but also supply protons to protons pumps. Net gain: 4 atp, 6c02, 10 nadh2, and 2fadh2, happens twice. The movement of h+(just a proton) out, carried by nadh2. When protons pump back in they create atp. Adp with oen organic phosphate molecules makes atp.
