Question

Water soluble hormones bind to plasma membrane receptors, which initiate a signal transduction pathway with which of the following processes?
First messenger hormone docking with plasma receptor
Activated protein kinase enzyme
Second messenger pathways including G proteins and phospholiapse C
Second messenger pathways including G proteins and adenylate cyclase Water soluble hormones bind to plasma membrane receptors, which initiate a signal transduction pathway with which of the following processes?

Explanation / Answer

Water soluble hormones such as epinephrine bind with plasma membrane receptors. This activates G protein which in turn stimulates adenyl cyclase enzyme causing increase in production of cAMP. cAMP stimulates protein kinase A which causes various cellular effects. So, the answer for this question is option 4 (second messenger pathways including G proteins and adenylate cyclase).
