Question

Which one of the following hormones is not involved in sugar metabolism ?

• A. Glucagon
• B. Cortisone
• C. Aldosterone
• D. Insulin

Answer 1

The correct option is C Aldosterone

Aldosterone is produced in the cortex of the adrenal glands, which are located above the kidneys. Aldosterone is responsible for regulating sodium homeostasis, thereby helping to control blood volume and blood pressure.

Insulin and glucagon are vital for maintaining normal ranges of blood sugar. Insulin allows the cells to absorb glucose from the blood, while glucagon triggers a release of stored glucose from the liver.

Medications known as glucocorticoids, such as prednisone and cortisone, are mainly used as anti-inflammatories. They are prescribed, for example, for an arthritis attack. One of their side effects is to increase blood glucose (sugar) since these drugs promote glucose production in the liver and reduce the sensitivity of the cells to insulin.
