Question

These hormones are commonly called catecholamines:

• A. Adrenaline and noradrenaline
• B. Thyroxine and calcitonin
• C. Somatotropin and prolactin
• D. Calcitriol and aldosterone

Hint:

Adrenaline and noradrenaline are the main catecholamines and are involved in the body’s fight-or-flight response.

Answer 1

The Correct Option is A

- Catecholamines are hormones produced by the adrenal glands, which include adrenaline (epinephrine) and noradrenaline (norepinephrine).
- Thyroxine and calcitonin are thyroid hormones, not catecholamines.
- Somatotropin and prolactin are pituitary hormones, not catecholamines.
- Calcitriol and aldosterone are hormones related to calcium and salt balance, respectively, and are not catecholamines.
