Energy used by the body to perform muscular contractions is called adenosine diphosphate, or ADP.
Bezzdna [24]

Answer:

The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.

During muscles contraction.The ATPs is broken down to ADP and Pi.

This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction

It is an exergonic reaction with production of heat.

Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.

Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)

Each bond breakin gives equal energy of -32kJpermol.
