A) catecholamines

Question

Quizplus · Accepted Answer

Membrane receptors are used by catecholamines, peptide hormones, and eicosanoids. These types of hormones cannot penetrate the cell membrane; therefore, they must bind to a receptor on the cell surface to initiate a signal transduction cascade inside the cell. Thyroid hormones, on the other hand, are lipid-soluble and can penetrate the cell membrane to bind to intracellular receptors.
