Study Notes
Muscle Energy and Contraction
- During rest, muscles utilize energy primarily from adenosine triphosphate (ATP).
- The major source of energy for muscle at rest and during recovery from contraction is creatine phosphate (CP).
- The phosphocreatine (PCr) system provides maximal muscle power for a period of 10 to 15 seconds.
- The immediate energy source for muscle contraction is adenosine triphosphate (ATP).
- Myosin is the muscle protein that acts as the enzyme adenosine triphosphatase (ATPase).
