Solution
The correct option is C Creatine phosphate
Creatine phosphate acts as the first source of phosphate group during muscle contraction. Creatine phosphate is converted into creatinine and high energy phosphate groups by creatine kinase enzymes. The high energy phosphate group binds with ADP molecules released from myosin head.
