Quizplus · Accepted Answer

All of the choices are correct. Binding of a chemical messenger with a cell's receptor can result in various types of cellular responses, including opening or closing of specific ionic channels in the plasma membrane, activation of an intracellular second-messenger system, promotion or inhibition of gene transcription, activation or inhibition of intracellular enzymes. The specific response depends on the type of chemical messenger, the receptor subtype, and the downstream signaling pathway involved.
