| Description: The reactions start in the cytoplasm and end in mitochondria. The reactions start in the cytoplasm and end in mitochondria. Aerobic Respiration glucose In the cytoplasm A The first stage, glycolysis, occurs in the cell‘s cytoplasm. Enzymes convert a glue 2 ATP . fl 4 ATP cose molecule to 2 pyruvate for a net yield (2 net) of 2 ATP! 2 NAD‘r combine with electrons and hydrogen ions during the reactions, so 2 NADH also form. 2 NADH 2 pyruvate In the Mitochondrion B The second stage occurs in mitochondria. The 2 pyruvate are convened to a molecule that enters the Krebs cycle. (302 forms and leaves the cell. 2 ATP, 8 NADH, and 2 FADH2 form during the reactions. 8 NADH, 2 FADH2 C The third and final stage, electron transfer phosphorylation, occurs inside mitochondria. 10 NADH and 2 FADH2 donate electrons and hydrogen ions to electron transfer chains. Electron flow through the chains sets up Electron Transfer hydrogen ion gradients that drive the fore Phosphorylation mation of ATR Oxygen is the final electron acceptor at the end of the chains. oxygen Picture Stats: Views: 47 Filesize: 206.34kB Height: 856 Width: 1428 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=49448 |
