Glucose
ATP

Heat

3. ATP Different organisms=Different energy sources
But all use a 2 step process to provide energy
First: Chemical energy from “food” is transferred to ATP.
Second: ATP is used to provide an energy source for cells.

4. ATP-Structure
Bond breaks=energy released

5. Cellular Respiration
Transfers chemical energy from glucose into chemical energy in ATP.
C6H12O6 + 6O CO2 + 6 H2O
29 ADP + 29 Pi ATP
Only 30% of energy goes to ATP; other = heat

7. Types of Cell Respiration
Aerobic: Requires O2
Anaerobic: No O2 = Fermentation
Alcoholic Fermentation: Glucose produces CO2 and 2 ethanol (CH2CH3OH)
Lactic Acid Fermentation: Glucose produces Pyruvate which becomes Lactic Acid (COOCHOHCH3)

8. Alcohol Fermentation

9. Lactic Acid Production

10. Photosynthesis Light energy converted to chemical energy
6CO2 + 6H2O sun 6O2 + C6H12O6
Thylakoids-turn light into ATP and NADPH
Calvin cycle: energy in ATP plus H convert CO2into 3 carbon molecule which becomes glucose and fructose.
Glucose + Fructose = Sucrose
