The energy source that is used to directly power muscle contraction is
|
|
lactic acid
|
|
|
ATP
|
|
|
oxygen
|
|
|
creatine phosphate
|
Explanation:
Detailed explanation-1: -The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.
