Electron Transport Essay Electron transport is the last phase and most important phase of cell respiration. It accounts for most of the ATP made in cell respiration. Cell respiration makes a total of thirty eight ATP’s, two from Glycolysis, two from the Krebs cycle and thirty four from electron transports. Electron transport takes place after Glycolysis and the Krebs cycle. Glycolysis and the Krebs cycle make their ATP through substrate level Phosphorylation while electron …showed first 75 words of 773 total…

The complex of proteins functions as a mill that harnesses the exergonic flow of hydrogen ions to drive the phosphorylation of ADP. Thus, an hydrogen ion gradient couples the redox reactions of the electron transport chain to ATP synthesis. This coupling mechanism for oxidative phosphorylation is called chemiosmosis a term that highlights the relationship between chemical reactions and transport across a membrane.
