Question:
Which one of the following is NOT a second messenger?
Which one of the following is NOT a second messenger?
Show Hint
Common second messengers are cAMP, cGMP, IP3 and calcium.
Updated On: Nov 13, 2026
- \(IP_3\)
- \(Ca^{++}\)
- cGMP
- \(Mg^{++}\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Second messengers carry the hormone signal inside the cell.
Step 2: List
Common ones are cAMP, cGMP, \(\text{IP}_3\), DAG and \(\text{Ca}^{++}\).
Step 3: Conclusion
\(\text{Mg}^{++}\) is not a second messenger.
Final Answer:
Magnesium ion is not a second messenger. \[ \boxed{\text{(D) }\text{Mg}^{++}} \]
