When nitric oxide is used in the dilation of smooth muscle cells, the factors that would interfere with the relaxation of the smooth muscle cells are the inhibitors of: (A) calcium release by the ER, (B) nitric oxide, (C) guanylyl cyclase, (D) calmodulin.
Nitric oxide is a chemical that is very essential for the health of an individual. It is a vasodilator i.e., it dilates the blood vessels. Nitric oxide is a colorless molecule that exists in gaseous form and has a chemical formula NO. It also acts as a neurotransmitter.
Calmodulin is protein that binds to the calcium for signaling processes. It binds to the calcium and relays the signals to enzymes that are sensitive to calcium levels in the body.
