Question (English)
Match the column — Half-life of hormones:
| TABLE-I (Hormone) | TABLE-II (Half-Life) |
|---|---|
| 1. Oxytocin | (a) 11 hours |
| 2. LH | (b) 6 days |
| 3. FSH | (c) 60 minutes |
| 4. hCG | (d) 2 minutes |
| 5. PMSG | (e) 170 minutes |
- 1-d, 2-c, 3-e, 4-a, 5-b ✓ Correct
- 1-d, 2-e, 3-c, 4-a, 5-b
- 1-c, 2-d, 3-e, 4-a, 5-b
- 1-d, 2-c, 3-a, 4-e, 5-b
Explanation:
Correct Answer: 1-d, 2-c, 3-e, 4-a, 5-b
The correct matching of hormones with their half-lives:
- Oxytocin: 2 minutes (shortest — nonapeptide, rapidly degraded)
- LH: 60 minutes
- FSH: 170 minutes (~3 hours)
- hCG: 11 hours
- PMSG: 6 days (longest — highest sialic acid content among all gonadotropins)
Correlation: Sialic Acid → Half-life
- PMSG has the highest sialic acid content → longest half-life (6 days)
- Oxytocin has no sialic acid (not even a glycoprotein) → shortest half-life (2 minutes)
Memory Aid
Ascending order of half-life: Oxytocin (2 min) → LH (60 min) → FSH (170 min) → hCG (11 hr) → PMSG (6 days)
