Choose correct statements about Muscarinic receptors;

a. An acetylcholine analog, In activated condition, these receptors slow the rate of heart muscle contraction.

b .This type of receptor is coupled to a Gαi protein, and ligand binding leads to the opening of an associated K+ channel.

c .The subsequent influx of K+ ions from the cytosol causes an increase in the magnitude of the usual inside-negative potential across the plasma membrane that lasts for several seconds.
