The energy for muscle contraction is most directly obtained from

Answer: it is obtained from Adenosine triphosphate (ATP).

Explanation:

In muscle metabolism, muscle need energy for contraction. This energy is obtained from the Adenosine triphosphate (ATP) present in the muscle. The muscle contain limited quantities of ATP. When it is depleted, ATP need to be resynthesize from other available sources like creation phosphate and muscle glycogen.

Metabolism is the total activities which take place in the body to create energy and other substances for its activities.

Answer: the energy for muscle contraction is directly obtained from ATP (Adenosine Triphosphate)

Explanation:

ATP is the body's biochemical way to store and transport energy. ATP is not stored in large quantities in the cells, hence the need for a quick production once muscle contraction starts. ATP could be produced from these three biochemical systems by the body. They include:

1.) Through the use of creatine phosphate

2.) Glycogen.

3.) Aerobic respiration.
