Structure and Function of ATP
What is ATP?
• ATP is the cell’s source of energy.
• It is used by almost all biological reactions that occur in your body.
Structure• 3 Parts:
– Adenosine (nitrogenous base)
– Ribose (sugar)– Three
Phosphates
Source of Energy
• During chemical reactions ATP gets broken down into ADP (Adenosine Di-Phosphate).
• The bond that holds the last phosphate group is broken.
• When this bond is broken energy is released.
ADP - ATP
• Energy is then needed to re-create the bond and form ATP
