1. Energy
ADP & ATP

2. What is Energy? Energy is the ability to do work.
Energy can be found in a number of different forms.
chemical energy,
electrical energy,
heat (thermal energy),
light (radiant energy),
mechanical energy, and
nuclear energy.

3. What is ATP? Adenosine Triphosphate
The principle compound used to store chemical energy used by all cells
Organic molecule containing high- energy phosphate bonds

4. Chemical Structure of ATP
Adenine
Ribose
3 Phosphate groups
High Energy Phosphate Bonds

5. Chemical Structure of ATP
Contains the nitrogen base adenine, a ribose sugar, and THREE phosphate molecules
Contains two, high-energy phosphate bonds

6. What does ATP do for you?
It supplies you with ENERGY!

7. How do we get energy from ATP?
By breaking the high- energy chemical bonds between the last two phosphates in ATP

8. How does ATP get made?
ATP gets made during a process called cellular respiration that takes place in both plants & animals.

9. What is ADP? Adenosine Diphosphate
Contains the nitrogen base adenine, a ribose sugar, and TWO phosphate molecules

10. How does ADP get made?
When your body needs energy, ATP breaks the bond between the last two phosphates.
This releases energy, a phosphate, and ADP

11. Releasing Energy From ATP
Adding a phosphate group to ADP stores energy in ATP
Removing a phosphate group from ATP releases energy & forms ADP
Lose
Gain

12. Cells Using Biochemical Energy
Cells Use ATP For:
Active transport
Movement
Photosynthesis
Protein synthesis
Cellular respiration
All other cellular reactions
