• Process which converts macromolecules into an energy form cells can use, ATP

• 3 Stages

Page 3: Cellular Respiration Converting Food Energy into Cell Energy

Cellular RespirationCellular RespirationStage 1: GlycolysisStage 1: Glycolysis

• Occurs in the cytoplasm of cells

• O2 not required (anaerobic)

• Some ATP produced• Net yield = 2 ATPs

Cellular RespirationCellular RespirationStage 2: The Krebs CycleStage 2: The Krebs Cycle

• Occurs in the mitochondria

• O2 required (aerobic)

• Some ATP produced• Net yield = 2 ATPs

Cellular RespirationCellular RespirationStage 3: Electron Transport ChainStage 3: Electron Transport Chain

• Occurs in the membrane of mitochondria

• O2 required (aerobic)

• A lot of ATP produced• Net yield = 32 ATPs

• 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
