Answer: Muscle contraction is the process that takes place when actin and myosin slide each other.
Muscle contraction starts with the process of generation of the action potential. This leads to the stimulation of muscles.
The active site of actin is exposed and calcium ion binds to the troponin.
After the myosin head forms a cross bridge with actin.
Myosin head bends and ADP and inorganic phosphate are released.
ATP attaches to myosin head and leads the cross bridge to detach.
ATP hydrolyses to ADP and inorganic phosphate.
