Vedclass · Answer

(D) Protein hormones are water-soluble and cannot cross the lipid bilayer of the plasma membrane. Therefore,they interact with specific receptors located on the cell-surface (membrane-bound receptors) to initiate their physiological response. This interaction generates second messengers like $cAMP$ or $IP_3$ inside the cell,which then regulate cellular metabolism. In contrast,steroid hormones,which are lipid-soluble,have intracellular receptors located in the cytoplasm or nucleus.
