Cell Energy: ATP Chapters 8 & 9

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

Adenosine Triphosphate

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

3rd phosphate is broken off

ATP breaking down to ADP and releasing ENERGY!

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!

ADP being recycled to create ATP once again.
