Q: Why is ATP useful to cells? 8.1 Energy and Life p226 Q: Why is ATP useful to cells? A: ATP can easily release & store energy by breaking and re-forming the bonds between its phosphate groups. This characteristic of ATP makes it exceptionally useful as a basic energy source for all cells.

Chemical Energy and ATP Adenosine triphosphate (ATP) Storing Energy(ADP like partially charged battery) Releasing Energy-breaking off the phosphate group Used in: active transport, protein synthesis

ATP as a charged battery ADP has some energy, but needs more. When 3rd phosphate is added, it becomes ATP, fully charged.

How are ATP and ADP diff?
