Question
Chapter 8, Problem 2Q
Summary Introduction
To review:
The action of chromium metal ion as a cofactor or as an allosteric activator in response to its effect exerted on the insulin hormone activity.
Introduction:
Insulin hormone is involved in the regulation of glucose level of blood and is produced by the beta cells present in pancreatic islets. The hormone enhances uptake of glucose by the skeletal muscle and adipose cells.

The NO diffuses out of the endothelial cells and into smooth muscle cells that are in close proximity. In the smooth muscle cells, NO binds to an enzyme, X, to rapidly increase intracellular levels of Y. Y causes rapid relaxation of smooth muscle cells surrounding the blood vessels. The actions of the Y molecule are controlled by enzyme Z which degrades protein Y into a non-functional form, blocking vasoconstriction and retaining high blood flow. Identify molecules X, Y and Z and explain how the drug Viagra targets this pathway.arrow_forward“Hitting the wall” is a term marathon runners use to describe their body’s reaction once their liver and muscle cells have run out of glycogen.
