Question

During stressful situations, the adrenal gland releases large amounts of into the blood stream.

• A. Catecholamines
• B. Monoamines
• C. GABA
• D. Dopamine

Hint:

Stress: hormones released by the adrenal gland are catecholamines (adrenaline and noradrenaline). Option 1.

Answer 1

The Correct Option is A

Step 1: Spot the gland and the situation.
The question names the adrenal gland and stress. This points to the fight or flight response, which is run by the adrenal medulla.

Step 2: Recall the hormones involved.
In this response the medulla releases adrenaline and noradrenaline. Chemically both are catechol based amines, so the textbook groups them as catecholamines.

Step 3: Match the group with the options.
Only option (1) names this group directly. The other options name a broader class, an inhibitory brain chemical and a single brain transmitter.

Step 4: Why the other options fail.
Monoamines is too general to be the stated answer. GABA lowers nerve firing and is made in the brain, not the adrenal gland. Dopamine is only one catecholamine and mainly acts in the brain, so the group name is the better answer.

Step 5: Check with the effect.
Raised heart rate, fast breathing and more blood sugar during stress are all effects of adrenaline and noradrenaline. This fits catecholamines.

Step 6: Quick recap of the reasoning.
We first understood what the question asks, then matched the key fact from the chapter with each option one by one, and finally dropped the options that belong to a different idea. This habit of linking every option to its own concept helps avoid careless slips in similar questions.

Final Answer:
Adrenaline and noradrenaline released by the adrenal gland are called catecholamines, so the answer is option (1).
