An explanation of the Genetic Code: DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) residues polymerized by dehydration synthesis in linear chains with specific sequences.
SIDE EFFECTS. Common adverse reactions to systemically administered epinephrine include anxiety, apprehensiveness, restlessness, tremor, weakness, dizziness, sweating, palpitations, pallor, nausea and vomiting, headache, and respiratory difficulties.
Both epinephrine and norepinephrine increase heart rate. During a bout of exercise, epinephrine exerts a significant vasodilatory effect on the blood vessels associated with the skeletal muscles. Corticosteroids, including cortisol, also have an effect on blood pressure. Without the presence of cortisol, the influence of epinephrine and norepinephrine upon vascular responses is minimized (Drew and Leach, 1971). Therefore, cortisol facilitates the action of the catecholamines.
