  1. Cellular RespirationConverting Food Energy into Cell Energy

  2. Cellular RespirationConverting Food Energy into Cell Energy • Process which converts macromolecules into an energy form cells can use, ATP • 3 Stages

  3. Cellular RespirationStage 1: Glycolysis • Occurs in the cytoplasm of cells • O2 not required (anaerobic) • Some ATP produced • Net yield = 2 ATPs

  4. Cellular RespirationStage 2: The Krebs Cycle • Occurs in the mitochondria • O2 required (aerobic) • Some ATP produced • Net yield = 2 ATPs

  5. Cellular RespirationStage 3: Electron Transport Chain • Occurs in the membrane of mitochondria • O2 required (aerobic) • A lot of ATP produced • Net yield = 32 ATPs

  6. A. Cytoplasm of the cell A. Mitochondrion A. Mitochondrial membrane Cellular RespirationReview…... Q. Where does each Stage occur? • 3 Stages: • Stage 1: Glycolysis • O2 not required (anaerobic) • Some ATP produced • Stage 2: Krebs Cycle • O2 required (aerobic) • Some ATP produced • Stage 3: Electron Transport System • O2 required (aerobic) • Much ATP produced 2 ATPs 2 ATPs 32 ATPs
