How are Hydrogen atoms moved from the Kreb Cylcle to the Electron Transport Chain?
Grade 11 Biology question

Hydrogen atoms produced from the Kreb Cycle are of a result of the product produced form the Krebs Cycle. As you know the Krebs Cycle takes away hydrogen atoms at different stages. As each hydrogen ion is removed, it is transported to the electron transport chain in the matrix of the mitochondria. The hydrogen ions serve as the energy drive for the Electron Transport Chain. Once one side has a higher hydrogen gradient, ATP can be produced through chemiosmosis. Most ATP is produced in the Electron Transport Chain.

while one examines the same old sum of reactions for cellular respiration C6H1206 + 6O2 --> 6CO2 + 6 H2O it style of feels sparkling that the hydrogens that finally end up as part of water (on the tip of the electron transport chain) come from the glucose molecules that initiate glycolysis. even with the undeniable fact that that's prevalent that, for each glucose, 12 pairs of hydrogens enter the electron transport chain; AND we additionally understand that all and sundry 12 of the oxygen atoms on the left side of the reaction arrow finally end up in the water molecules on the splendid, no longer in the carbon dioxide. consequently, a extra clever precis would be C6H1206 + 6O2 + 6H2O --> 6CO2 + 12 H2O. This makes it sparkling that 0.5 of the hydrogens come extremely from water molecules that are further alongside a thank you to three of the intermediate products of glucose breakdown. yet, all that aside, the easy answer to the unique question is probable meant to be "glucose".
