Where would you expect to find a receptor of a target cell for a peptide hormone?

Question

Quizplus · Accepted Answer

Peptide hormones are hydrophilic molecules that cannot pass through the hydrophobic plasma membrane of cells, so they bind to receptor proteins that are located on the surface of the target cell. These receptors transmit signals across the membrane and trigger intracellular signaling pathways. Therefore, the receptor for a peptide hormone would be found on the cell surface.
