The new variant of equation of metabolism as “Donators (first stage of proton conductance) + membrane - redox potentials three state line system + O2 (Hemoglobin of pulmonary capillary-8-th stage, Hemoglobin of tissue-87 trillion cell surrounded capillary-9-th stage,) + ADP + Pi + (H+ + nH + memb.space - proton gradient-4-th stage) = (ATP + heat energy-5 -th stage) + H2O (5-th stage) + (nH + matrix) + CO2(second stage of proton conductance)”, which give to us the possility to speak about of existing of two forms of free protons as at first : left side of equation - Н+ membrane space – formed by this reaction as - СНО- food molecules , separated from СНО - Н- hydrogen atom , separated from hydrogen atom free proton, free electron –proton gradient – at second : right side of equation H+ matrix is the main Molecular mechanism of the Membrane Redoxy Potential: A Three-State-Dependency Closed 9-Step Stepped Cycle of Proton Conductance. In such way all processes including from Sixth stage – to Ningh stage of proton conductance may be describe as carbon dioxide diffuses in to the plasma and red blood cells (in the tissue capillaries), carbon dioxide is released from red blood cells, proton is released from red blood cells (in the pulmonary capillaries), oxygen diffuses in to plasma from alveolus, oxygen binds to hemoglobin, in the chloride shift as HCO3 diffuses in to red blood cells, proton and carbon dioxide are combined with hemoglobin, that has released oxygen, promotes the release of oxygen from hemoglobin – oxygen diffuses out of red blood cells and plasma in to tissues – mitochondria of 87 trillion cells through oxygen channeling lipid based pathways.
