Which of the following is a second messenger?
AcAMP
BAdenylcyclase
CPhospholipase
DProtein Kinase
Answer:
A. cAMP
Read Explanation:
Cyclic adenosine monophosphate (cAMP) is a second messenger molecule that plays a role in many cellular processes, including: Signal transmission: cAMP is a second messenger that transmits signals from receptors to targets within a cell. Synaptic stimulation: The brain uses cAMP to convert synaptic stimulation into stored information. Immune response: cAMP levels can increase in clinical situations that lead to infection. Light signal transduction: In Anabaena cylindrica, cAMP acts as a second messenger for light signal transduction. Pollen tube growth: cAMP acts as a second messenger in pollen tube growth and reorientation.
