Document Summary
Bio 121 - week 8 - lecture 13 (pt. A 6-carbon glucose molecule is split into two 3-carbon molecules called g3p. To break the bond in glucose, you need to invest in molecules. The g3p molecules lose electrons to nad+ molecules. G3p molecules are lose electrons to nad+ molecules. G3p molecules lose electrons to nad+ molecules. The g3p molecules lose electrons to nad + molecules. G3p molecules are oxidized and nad+ is reduced to. The nadh electron accpetorscarry the electrons to the electron transport. Additional glycolysis reactions convert the oxidized g3p molecules to 3-carbon pyruvate molecules. This yields two molecules of atp per pyruvate moleucultive. After pay back he original two atp molecules invested at the start of glycolysis, the final yield is two atp molecules. Glycolysis therefore produces two net atp molecules, two nadh molecules, and two pyruvate molecules. Only a small amount of glucose chemical energy is harvested during this stage.
