Cellular Energy

• Energy: the ability to do work
• Living things obtain and use energy
• ATP: adenosine triphosphate
• ATP consists of adenine, ribose, and 3 phosphate groups

  
• ATP is one of the most important compounds that cells use to store and release energy
• ATP has three phosphate groups.
• Adenosine Diphosphate (ADP) has two phosphate groups
• The cell stores energy by converting ADP to ATP
• The cell releases energy by converting ATP to ADP
• ADP + Phosphate = ATP
• ATP is converted energy
• ATP can be used and charged again.
• Used energy becomes ADP
• Uses for ATP: powers active transport like nerve cells and protein pumps, moves individual cells, and communication.
