Document Summary

Two turns of the krebs cycle releases 4 co2 molecules. Where do the other 2 carbons go: released as co2 during glycolysis, released as co2 during pyruvate oxidation, they are incorporated into organic molecules in the cell, they are turned into energy. Answer b: with each formation of acetyl-coa, co2 is released from each g3p. Following the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, most of the energy from the original glucose molecule is found in _____: acetyl-coa, co2, pyruvate, nadh, atp. Answer d. energy transferred to nadh through the redox reactions. By the end of the krebs cycle, glucose is fully oxidized to co2 and free energy is stored in molecular management molecules. Answer: the movement of protons from high to low concentrations (diffusion). Answer: slower; feedback inhibition and higher rate of oxidation, pfk regulation;
