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
