When an action potential (nerve impulse) arrives at a muscle membrane (sarcolemma), in what order do the following events occur?
a. Release of Ca 2+ ions from the sarcoplasmic reticulum
b. Hydrolysis of ATP, with release of energy
c. Detachment of myosin from actin
d. Sliding of myosin along actin filament
e. Opening of switch 1 and switcH2 on myosin head
