Quizplus · Accepted Answer

Calmodulin complexes with calcium and acts as a second messenger in smooth muscle cells. Myosin and actin are contractile proteins found in muscle cells, troponin is a regulatory protein that helps regulate muscle contraction, and cAMP is a secondary messenger that regulates various cellular processes but is not directly involved in smooth muscle cell contraction.
