The interaction between actin and myosin in smooth muscle requires
A) the interaction between calcium and troponin to expose the myosin binding site on the actin molecule.
B) that the calcium-calmodulin complex directly phosphorylates myosin light chain, allowing myosin to bind to actin.
C) that the calcium-calmodulin complex activates myosin light-chain kinase, which phosphorylates myosin thereby allowing it to bind with actin.
D) the tropomyosin must be moved out of the way by troponin before myosin can bind to actin.
E) the activation of troponin, which stimulates myosin light-chain kinase to phosphorylate myosin light chain, allowing myosin to bind with actin.
