Cells that respond to peptide hormones usually do so through a sequence of biochemical reactions involving receptor and kinase activation.In order for cells to respond,it is necessary for first and second messengers to communicate.This is possible because .

Question

Quizplus · Accepted Answer

G proteins act as the link between first and second messengers in the sequence of biochemical reactions that occur in response to peptide hormone signaling. When a peptide hormone binds to its receptor on the cell membrane, it activates a G protein, which then activates a second messenger, such as cAMP or IP3. This second messenger then triggers a series of downstream biochemical reactions, ultimately leading to the intended cellular response.
