Contrast the role of Ca2+in the contraction of a skeletalmuscle fiber and a smooth muscle cell.
Describe the regulation of smooth muscle contraction by intracellular calcium and how cross-bridge cycling is terminated when calcium decreases again.
Discuss the similarities and differences by which Ca2+ activity is involved in initiating muscle contraction in skeletal versus smooth muscle fibers (hint: include Ca2+ sources, proteins it binds to, and signaling cascade it activates leading to contraction). (please explain in sentences, max 12 sentences)
