Transcript

  • Cellular RespirationConverting Food Energy into Cell Energy

  • Cellular RespirationConverting Food Energy into Cell EnergyProcess which converts macromolecules into an energy form cells can use, ATP3 Stages

  • Cellular RespirationStage 1: GlycolysisOccurs in the cytoplasm of cellsO2 not required (anaerobic)Some ATP producedNet yield = 2 ATPs

  • Cellular RespirationStage 2: The Krebs CycleOccurs in the mitochondriaO2 required (aerobic)Some ATP producedNet yield = 2 ATPs

  • Cellular RespirationStage 3: Electron Transport ChainOccurs in the membrane of mitochondriaO2 required (aerobic)A lot of ATP producedNet yield = 32 ATPs

  • Cellular RespirationReview...3 Stages:Stage 1: GlycolysisO2 not required (anaerobic)Some ATP producedStage 2: Krebs CycleO2 required (aerobic)Some ATP producedStage 3: Electron Transport SystemO2 required (aerobic)Much ATP produced

    Q. Where does each Stage occur?2 ATPs2 ATPs32 ATPs
