• A. Insulin
• B. Thyroid hormones and catecholamines
• C. Melatonin
• D. Glandins and prostaglandin

Hint:

Tyrosine-derived hormones:
Thyroid hormones, catecholamines.
Tryptophan: melatonin, serotonin.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Hormones are derived from different precursors.
Tyrosine is a precursor for specific hormones.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the hormones derived from tyrosine.

Step 3: Detailed Explanation:
Tyrosine is the precursor for:
- Thyroid hormones (T3, T4)
- Catecholamines (epinephrine, norepinephrine, dopamine)
Insulin is a peptide hormone.
Melatonin is derived from tryptophan.
Prostaglandins are derived from arachidonic acid.
Thus, thyroid hormones and catecholamines are derived from tyrosine.

Step 4: Final Answer:
Thyroid hormones and catecholamines are derived from tyrosine.
Hence, the correct option is (B).
