How do glucocorticoids enable the body to deal appropriately with stress? by releasing the neurotransmitters that prepare the bo
klemol [59]

Answer:

By increasing blood glucose, fatty acid, and amino acid levels

Explanation:

Cortisol, corticosterone, and cortisone are the glucocorticoids released by the adrenal cortex and serve to impart resistance to stress. These hormones stimulate protein breakdown (mainly in muscle cells), gluconeogenesis and lipolysis and thereby increase the concentration of amino acids, glucose and fatty acids in blood.

The amino acids are used by cells for synthesis of new proteins or for synthesis of ATP. Glucose is also used by cells to produce ATPs.

Glucocorticorticoids increase the sensitivity of blood vessels for hormones which in turn stimulate their constriction. The vasoconstriction raises blood pressure. The process of vasoconstriction resumes the normal range of blood pressure which is otherwise dropped by some emergency conditions such as injury and severe loss of blood.
