- Hormone A, which enters the cell and binds to a nuclear receptor, is likely lipid-soluble because lipid-soluble hormones can pass through the cell membrane to bind to intracellular receptors. Hormone B, which binds to a membrane receptor, is likely water-soluble and can stimulate signal transduction pathways, such as the activation of a G protein, on the outside of the cell.
