Q. The functions of tropomyosin in skeletal muscle include: (Solved)
1. releasing Ca2+ after an action potential
2. sliding on actin to produce shortening
3. binding to myosin during contraction
4. acting as a “releasing protein” at rest by covering up the sites where myosin binds to actin
5. generating ATP which passes to the contractile mechanism
- d. acting as a “releasing protein” at rest by covering up the sites where myosin binds to actin
