A) Only liver cells contain the genes that encode the receptor proteins for all four hormones.
B) Skeletal muscle cells use fewer signal transduction pathways than liver or skin cells.
C) All four cell types express receptors for all four hormones, but only liver cells actually respond to all of them through signal transduction pathways.
D) Liver and skeletal muscle cells have different functions in the body and therefore do not express any of the same hormone receptors.
E) The biological activities of liver and skin cells are not identical, but they share receptors to two of the same signaling molecules.
