1. Cell Energy: ATP
Chapters 8 & 9

3. Energy for the Cell
ATP= Adenosine Triphosphate
3 major parts to ATP:
1. Adenine
Adenosine
2. Ribose (sugar)
3. Three phosphates

4. Adenosine Triphosphate

6. How is energy released from ATP?
Break a bond between 2nd & 3rd phosphates
This releases ENERGY to be used by cells!

7. 3rd phosphate is broken off

8. ATP breaking down to ADP and releasing ENERGY!

9. ADP= Adenosine Diphosphate
Only 2 phosphates instead of 3
ADP is recycled to make ATP [add a phosphate]
If ADP/ATP is not reused, we would eat 24/7 just to have enough energy!

10. ADP being recycled to create ATP once again.
