Adenosine Triphosphate. Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do.denosine Triphosphate.

The role ATP plays in muscle contraction is that ATP binds to sites  on myosin heads, inducing a conformational change in the actin  binding site and reducing the affinity f â¦ or the actin substrate.  Hydrolysis of ATP then cocks the myosin head and moves it closer to  the z disk.he role ATP plays in muscle contraction is that ATP binds to sites  on myosin heads, inducing a conformational change in the actin  binding site and reducing the affinity f â¦ or the actin substrate.
