Quizplus · Accepted Answer

Receptor molecules on the surface of a cell may allow a particular ligand to bind and determine that cell's response. Therefore, both options A and B are correct, making D the best choice. Option E is incorrect because receptors do not bind to all ligands, but rather, they have specificity for certain ligands.
