Unit IV: Cell Energy

Part III: Cellular Respiration

What cells use cellular respiration?

Where Does Cellular Respiration Occur?

Cellular Resp. Cellular Respiration: process by which mitochondria break down food (glucose) molecules to produce ATP 3 different phases: glycolysis, citric acid cycle and electron transport chain

Phases Anaerobic: Oxygen is NOT required Aerobic: Oxygen is required 1st Stage: Glycolysis Aerobic: Oxygen is required 2nd Stage: Citric Acid Cycle 3rd Stage: Electron Transport Chain

Glycolysis Breaks down glucose Creates 2 ATP ANAEROBIC!! Occurs in the cytoplasm Where do we get this glucose? Where do plants get this glucose?

Citric Acid Cycle Breaks down glucose Creates 1 ATP AEROBIC Occurs in the mitochondria

Electron Transport Chain Creates 32 ATP AEROBIC Occurs in the mitochondria

Efficiency Aerobic process is more effective! Anaerobic processes can produce ATP for short periods of time in the absence of oxygen BUT not enough to keep cells alive

Chemical Equation C6H12O6 + 6O2 ➜ 6CO2 + 6H2O + ATP Carbon Dioxide Energy Glucose Oxygen Water

Cellular Respiration Photosynthesis Plants Sunlight required Food accumulated Energy from the sun stored in glucose Carbon Dioxide taken in Oxygen given off Produces glucose & oxygen from carbon dioxide, water and sunlight 2 phases: light-dependent & light-independent Occurs in chloroplasts & chlorophyll All living cells, even plants! Sunlight not required Food broken down Energy of glucose released Carbon Dioxide given off Oxygen taken in Produces ATP, water & carbon dioxide from glucose & oxygen 3 phases: glycolysis, citric acid cycle & electron transport chain Occurs in cytoplasm & mitochondria
