BIO-1801 Lecture Notes - Lecture 19: Acetyl-Coa, Oxidative Phosphorylation, Citric Acid Cycle
Document Summary
Start with glucose cutting fructose-1,6-biphosphate (final product from step 1) into 2 g3p harness some of the energy. Nadh is receiving electrons (reduced) produce two molecules of pyruvate which occurs in the cytosol. Glycolysis two molecules, nadh and atp, ultimate product is atp: energy investment step (step 1, cleavage step, energy liberation step, substrate level phosphorylation: atp produces by stripping a phosphate off a molecule. Clicker question: substrate level phosphorylation differs from photophosphorylation. Glycolysis product moves on: heading to the citric acid (krebs) cycle, nad+ + e- yields 3 nadh, atp, 1 fadh2, at the end of the krebs cycle, for each glucose molecule, oxidative phosphorylation. Nadh: 2 (splitting of glucose) + ( 2 acetyl coa) + 2(3 for every turn) = 10. Fadh: 2 chemiomosis: recognize that there is a hydrogen ion gradient here phosphorylation: making of atp. 3c pyruvate is converted into 2c acetyl coa.
