How Is Smooth Muscle Contraction Different From Skeletal Muscle Contraction? Stimulation of both muscle cells lead to an increase in cytosolic calcium. … In skeletal muscle, calcium causes tropomyosin to shift, exposing the myosin-binding site on actin and starting contraction. In smooth muscle, calcium activates a kinase that phosphorylates light chains on myosin, leading to
