Quizplus · Accepted Answer

Receptors are specific to the signal ligand, meaning that they will only bind to a specific molecule or group of molecules. While some receptors are found on the surface of cells, others are located within the cell itself. Not all receptors act as ion channels, as there are many different types of receptors with varying functions. Therefore, options A, C, and D are not entirely accurate.
