The problem of regenerating NAD+: 2 Solutions - the 3% Solution: Anaerobic Respiration - the 50% Solution: Aerobic Respiration The Oxygen Revolution and Aerobic Respiration Endosymbiotic Theory -Mitochondria and Chloroplasts Krebs Cycle completely oxidizes sugar (and fat, amino acids, etc) - some energy coupled to GDP + Pi -> GTP Electron Transport Chain takes e- from NADH & reduces O2 to H2O -solution to the problem of toxic O2 • Oxidative Phosphorylation = Electron Tranport + ATP formation - electron transport = energy to pump H+ across membranes - The Proton Motive Force - ATP synthase = H+ driven ATP “generator” Aerobic respiration = Very efficient! major source of ATP from fuel Respiration Metabolism and Food: Making Connections Aerobic Metabolism: Why do we breath Oxygen in?
