Krebs cycle andthe membrane redoxy potential three state dependent 9 stepped full cycle of proton conductance, described by usare more similar each other in a closed loop figures, unlike glycolysis, the citric acid cycle is a closed loop: last step in the citric acid cycle regenerates oxaloacetate by oxidizing malate, meanwhile first step of Krebs cycle is a condensation step, combining the two - carbon acetyl group (from acetyl CoA) with a four - carbon oxaloacetate molecule forms a six - carbon molecule of citrate, which is used in the first step as proton, electron donators. Similar to Krebs cycle, the membrane redoxy potential three state dependent 9 stepped full cycle of proton conductance, described by us also have a closed loop figure. In the last ninth stage of the membrane redoxy potential three state dependent 9 stepped full cycle of proton conductance, proton combine with hemoglobin (generation of HbH), which promotes the release of oxygen from hemoglobin, oxygen diffusion to all cells conditioning the release of proton, electron from food substrates as proton, electron donators in the 1-stage of closed cycle, described by us, also proton released from hemoglobin promotes uptake of oxygen by hemoglobin, CO2 promotes the generation of free proton by mecchanism as H2CO3- = H+HCO3, carbonic anhydrase catalyzes the formation of CO2 from H2CO3 and CO2 diffuse out in the alveoli in the last stage of closed loop figured cycle of proton conductance.
