Summary of Skeletal Muscle Contraction (6-8)
6.  AP in T tubules cause SR to release Ca2+
7.  Ca2+ binds to troponin (of thin myofilament).  Causes tropomyosin-troponin complex to move, exposing myosin binding sites on actin
8.  Muscle contraction requires energy.  ATP bound to myosin are broken down into ADP + P, releasing energy, which is briefly stored in the “cocked” myosin head
