Question : What is the source of energy for muscle contraction ?

1.	Question : What is the source of energy for muscle contraction ?
Answer» Solution :ATP is source of energy for muscle contraction. In each myosin MOLECULE ATPase enzyme is present at the HEAD region. In the presence of this enzyme along with `Ca^ (2+)` and `Mg^ (2+)` ions. ATP molecule dissociate into ADP + PI and energy is released from the head of myosin with the energy obtained from ATP, excited myosin forms cross-bridge with actin and muscle contraction is INITIATED.
