1. only contraction is energy requiring, not relaxing
2. sequestering of Ca2+ causes separation of actin-myosin bands and muscle relaxation
3. ATPase clefts are on the tips of the myosin beads
4. ryanodine receptors are voltage gated Ca2+ chains
5. Troponin T inhibits the interaction of actin and myosin
- b. sequestering of Ca2+ causes separation of actin-myosin bands and muscle relaxation
