1. Ca2+ released from SR in response to neural stim triggers muscle contraction + activates phosphorylase (thus promoting glycogenolysis) 2. Plasma levels of Epi/NE increase markedly (promotes glycogenolysis + lipolysis) 3. During strenuous exercise, energy demands cannot be met by aerobic metaboli...
CVDs encompass a wide spectrum of disorders, including diseases of the heart muscle and the vascular system that supplies the brain, heart, and other vital organs with blood and oxygen. CVDs are the preeminent cause of death worldwide, claiming the lives of an estimated 17.9 million people annu...
3-DPG (diphosphoglycerate), a byproduct of red blood cell metabolism. West suggests that “a simple way to remember these shifts is that an exercising muscle (increased metabolic demand), is acid, hypercapnic and hot, and it benefits from increased unloading of oxygen from its capillaries.”8...

In the late 1980s, Furochgott and Zawadzki (1980) found that vascular endothelial cells produce a substance which may induce vascular smooth muscle relaxation. In 1987, it was confirmed, and named the CM 17 endothelial cell-derived relaxing factor (EDRF)[18]. Subsequently, it was discovered ...
