1. Releasing the Stored Energy: Cellular Respiration

3. Cellular Respiration
Breaking down nutrients in the prescence of oxygen to form usable energy (ATP).
Used by unicellular and multicellular organisms.
Used by plants and animals.
Happens in the mitochondria

4. Cellular Respiration Glucose pyruvic acid
water+ carbon dioxide+ 38ATP
C6H12O6  P.A.  6H2O + 6 CO2 + 38ATP

5. Cellular Respiration has 3 stages
Glycolysis
The Citric Acid cycle
The Electron Transport Chain

6. 1. Glycolysis

7. Glycolysis Anaerobic (needs no oxygen) takes place in the cytoplasm
uses up 2 ATP
produces 4 ATP
2ATP + glucose  2 pyruvic acid + 4 ATP

8. 2. The Citric Acid Cycle

9. The Citric Acid Cycle Aerobic (needs oxygen)
takes place inside the mitochondria
Produces 2 ATP

10. 3. The Electron Transport Chain

11. The Electron Transport Chain
Aerobic (needs oxygen)
A series of complex reactions
takes place in the membranes of the mitochondria
produces 34 ATP
