The Citric Acid Cycle Acetyl Coenzyme A??-? A small molecule that carries acetyl functional groups in cells. Composed of an acetyl group attached to a coenzyme A molecule. The starting product of the citric acid cycle. Acontinase??-? The citric acid cycle enzyme responsible for catalyzing the reaction that converts citric acid to isocitrate with the release of water. Adenisine Triphosphate (ATP)??-? The molecule from which cells derive energy. Comprised of an adenisine molecule bonded to three phosphates, each phosphate bond contains energy, especially the third bond. By breaking that one bond and reducing ATP to adenisine?diphosphate (ADP), the cell can get the energy to carry out its various processes.

Why? Where? In Out Glycolysis Split Glucose into 2 pyruvates Cytosol 1 Glucose 2 Pyruvate 2 NADH 2 ATP Transition Reactions Pyruvate to Acetyl-CoA Inner membrane 2 Pyruvate 2 Acetyl-CoA 2CO2 2NADH Citric Acid Cycle Make the electron carriers Mitochondrial Matrix Acetyl-CoA 2 ATP 6NADH 2FADH2 4CO2 Oxidative phosphorylation (ETC) & Chemiosmosis Send H+ in inner membrane space as they go down ETC chain and this allows us to manage energy (create concentration gradient and produce most ATP) ETC- Cristae Chemiosmosis- inner membrane NADH & FADH2 2H2O 36-38 ATP *** Out products are per glucose *** ***If you want per pyruvate take half of what the numbers are in the chart*** Delivery System (follow the vesicle)
