One important feature of the presence of multiple, different nAChR subunits is that the subunits
A) vary among different individuals.
B) can "fill in" for one another, for example if one fails to function.
C) similarly affect how selective the channel is to different ions.
D) differentially affect how selective the channel is to different ions.

Question

Quizplus · Accepted Answer

Different nAChR subunits can have different effects on ion selectivity, meaning that different combinations of subunits can produce channels with different ion selectivities. This allows for a great deal of flexibility in the function of nAChRs.
