In glycolysis of cellular respiration, the pyruvate amounts to c^3h^4o^3. the amount for carbon and oxygen make sense as there are two pyruvates and together they amount to 6 carbons and 6 oxygens (the amount glucose has), but the amount of hydrogens don't add up. there are 8 in total (from both pyruvates) and 2 going to nadh, but that amounts to 10 hydrogens, not 12. are the other two hydrogens used during glycolysis elsewhere? are they released in a different form? am i missing something? ?

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
