Adenosine Triphosphate and Energy Transfer

• Adenosine triphosphate (ATP) is a compound which stores energy. Often known as the energy currency. It's breakdown gives energy. In the body we have 85g of ATP in the body which lasts 2 seconds.
• An advantage of ATP is it is immediately available.
• An advantage of ATP is it is high intensity.
• An advantage of ATP is it can be resynthesised.
• A disadvantage of ATP is it only lasts 2-3 seconds.
• Breakdown of ATP:

  ATPase is the enzyme used to break down ATP. ATP is broken down into adenosine diphosphate and a single phosphate molecule. This occurs by an exothermic reaction.

  ATP=ADP+Pi+energy
• Resynthesis of ATP:

  For ATP to be rebuilt an endothermic reaction has to occur. ATP is re-synthesised from ADP and a single molecule combining.

  ADP + P = ATP
• ATP is resynthesised by using ADP Phosphorylation and energy.
