The energy needed for muscle contraction comes from ____
|
|
soda
|
|
|
calcium
|
|
|
myosin

ATP
|
Explanation:
Detailed explanation-1: -The energy required for muscle contraction is provided by the breakdown of ATP but the amount of ATP in muscles cells is sufficient to power only a short duration of contraction.
Detailed explanation-2: -Adenosine triphosphate (ATP) is the sole fuel for muscle contraction.
Detailed explanation-3: -During muscle contraction, chemical energy is converted to mechanical energy when ATP is hydrolysed during cross-bridge cycling. This mechanical energy is then distributed and stored in the tissue as the muscle deforms or is used to perform external work.
Detailed explanation-4: -Muscle contraction occurs via metabolism of adenosine triphosphate (ATP) derived primarily from the simple sugar glucose.
