Overview: Cellular respiration occurs in three main stages Stage 3: Oxidative phosphorylation –At this stage, electrons are shuttled through the electron transport chain –As a result, ATP is generated through oxidative phosphorylation –(oxidation of NADH to NAD and phosphorylation of ADP to ATP) Occurs Across Inner Mitochondrial membrane –This stage Occurs Across Inner Mitochondrial membrane Pyruvate Citric Acid Cycle Electrons CO 2 Electron Transport Chain O2O2 H2OH2O ATP Oxidative Phosphorylation Mitochondria Chemiosmosis
