Question

Where dose a muscles recieve the energy from to contract

Answer 1

The source of energy that is used to power the movement of contraction in workingmuscles 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 oncemuscle contraction starts, the making of more ATP must start quickly.

Answer 2

Muscles​ does receive​the energy from the food we eat. After the break down of glucose molecules with the help of oxygen lot of energy is released. That energy stored in ATP.

This energy is used.
