What is aerobic respiration?

The release of energy from food which requires the presence of oxygen.
What is the aerobic respiration equation?

C6H12O6 + 6O2 -> 6H2O + 6CO2 + 2820 kJ
How much energy is released from aerobic respiration?

2820 kJ
What is energy stored as?

Energy released from aerobic respiration is stored as ATP (which is an immediate source of energy in the cell).
What does ATP stand for?

ATP: Adenosine Triphosphate
What is ATP?
- Is an energy courier as it is very soluble and diffuses rapidly. (Aka energy currency)
- Found in all cells
- Role in the transfer of energy.
What 3 things combine to form ATP?

ADP + P + energy = ATP
What is the structure of ATP?
- Adenine —- Ribose — P — P — P
- (base) (5c sugar)
