A protein receptor that responds to a water soluble hormone in the blood would be found on the plasma membrane of the target cell, as these hormones cannot pass through the hydrophobic interior of the phospholipid bilayer that forms the membrane. Instead, they bind to a specific receptor protein on the outside of the cell membrane, triggering a signaling cascade inside the cell.
