Which one of the following pairs of hormones are examples of those that can easily pass through the cell membrane of the target cell and bind to a receptor inside it?

Lipid-soluble hormones, such as steroid hormones (Cortisol, Testosterone, Estrogen) and iodothyronines (Thyroxine), can easily pass through the lipid bilayer of the cell membrane and bind to intracellular (nuclear) receptors. Protein/peptide hormones (Insulin, Glucagon) bind to membrane-bound receptors.
