Krebs Cycle The Krebs cycle can be summarized by either of the diagrams below. The diagram below occurs twice, once for each acetyl CoA. When acetyl CoA attaches to a C 4 molecule in the Krebs cycle, the Coenzyme A is released. Two acetyl CoA molecules are consumed to produce 4 CO 2 , 2ATP, 6 NADH and 2 FADH 2 . The ATP molecules are produced by substrate-level phosphorylation. The diagram below also summarizes the Krebs Cycle. Electron Transport and Oxidative Phosphorylation Mitochondrion structure The inner membrane forms folds called cristae . These folds contain the carriers of the electron transport system. Acetyl CoA formation and the Krebs cycle occur in the inner space called the matrix. The space outside the inner membrane is the intermembrane space . The electron transport system pumps hydrogen ions (H + ) into this space for oxidative phosphorylation. Oxidative Phosphorylation The electron transport system is found in the mitochondrion and chloroplast of eucaryotes and in the plasma membrane of procaryotes. It consists of a series of carrier molecules which pass
