A hormone not involved in glucose metabolism is:
a. Glucagon
b. Cortisone
c. Aldosterone
d. Insulin

Guida verificata passo dopo passo

Step 1: Understand the role of each hormone listed in the options with respect to glucose metabolism. Glucose metabolism involves hormones that regulate blood sugar levels either by increasing or decreasing glucose in the bloodstream.

Step 2: Recall that glucagon is a hormone that raises blood glucose levels by promoting glycogen breakdown in the liver, so it is involved in glucose metabolism.

Step 3: Recognize that cortisone (a glucocorticoid) influences glucose metabolism by promoting gluconeogenesis and increasing blood glucose levels during stress.

Step 4: Identify that insulin lowers blood glucose levels by facilitating cellular uptake of glucose, making it a key hormone in glucose metabolism.

Step 5: Note that aldosterone primarily regulates sodium and potassium balance in the kidneys and does not have a direct role in glucose metabolism, making it the hormone not involved in glucose metabolism.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Glucose Metabolism

Glucose metabolism refers to the processes by which the body breaks down glucose to produce energy or stores it for future use. Hormones regulate blood glucose levels by promoting glucose uptake, storage, or release, ensuring energy balance.

Introduction to Metabolism

Role of Insulin and Glucagon

Insulin and glucagon are key hormones in glucose metabolism. Insulin lowers blood glucose by promoting cellular uptake and storage, while glucagon raises blood glucose by stimulating glucose release from the liver.

Function of Aldosterone

Aldosterone is a hormone involved in regulating sodium and water balance in the body, primarily affecting blood pressure. It does not play a direct role in glucose metabolism, distinguishing it from hormones like insulin and glucagon.
