The Hypothesized Value in Hemoglobin's Ability to Bind and Transport

The hypothesized value in hemoglobin's ability to bind and transport nitric oxide is

A) It allows hemoglobin to resist the effects of small pH changes as buffer molecule
B) By circulation into peripheral vessels it will trigger vasodilation to improve local blood flow
C) As it circulates it promotes smooth muscle of arteries and arterioles to contract, to increase blood pressure as needed
D) It acts as an enzyme cofactor necessary to maintaining a "clean and smooth" endothelial lining within blood vessels
E) It provides a mechanism upon which additional electrolytes can be transported to deficient tissues in the body
