• A)NO activates guanylyl cyclase,which catalyzes the synthesis of cGMP,which acts as an intracellular messenger in a pathway leading to smooth muscle relaxation.
• B)NO activates a protein kinase which catalyzes the synthesis of cGMP,which acts as an intracellular messenger in a pathway leading to smooth muscle relaxation.
• C)NO inhibits guanylyl cyclase,which allows the build up of cGMP,which acts as an intracellular messenger in a pathway leading to smooth muscle relaxation.
