Intracellular and extracellular _____ concentrations are the major determinants of the RMP.

Chemical Events during Muscle Contraction: No answer _____

After the power stroke in muscle contraction, binding of a new _____ molecule causes detachment of the myosin head from the actin filament

Slow twitch muscle fibers are _____ due to increased myoglobin concentration

Hint: (color)

_____ is absent in smooth muscle but present in skeletal muscle

Hint: Micro-component

Fast twitch muscle fibers are _____ due to decreased myoglobin concentration

Hint: (color)

During muscle contraction:- the _____ and I bands, and distance between Z bands, are shortened- the A band remains the same length
