ATP or Adenosine triphosphate is well know for it's energy source but despite it has many roles in cell. ATP is primarily used as energy source as it has higher energy in it's phospho-di-ester bonds between P and P atoms. It is hydrolyzed to ADP & AMP to give energy.
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
