Chapter 15, Problem 9DYKB
Summary Introduction
Introduction:
There are two categories of receptors that are cholinergic. These are the muscarinic and nicotinic receptors. The muscarinic and nicotinic receptors have been named and differentiated because those molecules, which are similar to acetylcholine, binds to them and triggers their stimulation process.

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