Final answer:
The secretion of glucocorticoids often leads to increased gluconeogenesis and higher availability of fatty acids for energy, but not directly to reduced plasma levels of sex steroids, increased blood flow, or all the listed effects.
Step-by-step explanation:
The secretion of glucocorticoids results in several physiological changes in the body. One of the primary effects is the increased conversion of protein to glucose, a process known as gluconeogenesis. In addition, glucocorticoids promote the greater availability of fatty acids as sources of energy and they are known to suppress the immune system's inflammatory response. While they do not directly affect blood flow, glucocorticoids can influence blood volume or blood pressure indirectly through various mechanisms. Secretion of glucocorticoids may not necessarily reduce plasma levels of sex steroid hormones directly, but chronic high levels may have effects on gonadal function. Therefore, the most accurate options from the provided list that glucocorticoids result in are increased conversion of protein to glucose (2) and greater availability of fatty acids as sources of energy (3).
