Which of these is a second messenger?
Open in App
Solution
The correct option is B cAMP
Second messengers are the intracellular molecules released by the cell in response to exposure to extracellular molecules i.e. first messengers. Extracellular molecules trigger the release of the secondary messengers.- The cAMP is a derivative of the ATP. It is used for many intracellular signalling pathways.
- ATP is a nucleotide. It is created during respiration in the mitochondria of eukaryotic cells.
- AMP is nucleoside triphosphate i.e. a type of nucleotide. AMP is used as a monomer of RNA, also used to generate ATP.
- GMP is a nucleotide, that is used as a monomer of RNA
So, the correct answer is 'cAMP'
