Which statement about nicotinic acetylcholine receptors (nAChRs) is true? Group of answer choicesEach nAChR is composed of seven different protein subunits.They are ionotropic receptors and conduct Na+ and Ca2+ ions across the cell membrane causing depolarization and a fast excitatory response.They are ionotropic receptors and conduct Cl- ions across the cell membrane, causing depolarization and a fast excitatory response.They are found in all areas of the nervous system except the brain.
