Fumarate

... it was already "common sense" to the scienstists at that time that the cirtrate->isocitrate->alpha-ketoglutarate->succinate->fumarate->malate->OAA. But a small amount of any of the intermediate would result in increasing the total reaction significantly. So Krebs proprosed ...

... molecules of H2O for every pyruvate that enters it. Equation : C3H4O3 + 3H2O = 3CO2 + 10 H (for ETS). Yes, 1 molecule of H2O will be releases when fumarate turn to malate. The other 2 H2O, I am not sure. Sham

... 2 extra molecules of water are produced this way). On the other hand the Krebs cycle uses up 2 molecules of water per glucose when it turns fumarate into malate. The answer to your question lies at the electron transport chain. i have been killing my brains trying to figure out how. I know ...

... divide GTP, in GDP+P and forms a bond between aspartate and IMP, forming adenilosuccinate. 2) Enzyme adenilosuccinate liasis eliminates fumarate from adenilosuccinate, producing AMP (o adenine). The guanine is generated by two reactions: 1)IMP is deidorgenated, and the H+ from IMP reduces ...
