Ion channels achieve selectivity in transport through all of the following mechanisms EXCEPT:
A)evolution from distinct and different parent proteins.
B)divergent evolution from a single type of channel protein.
C)low activation energy for selective passage of the dehydrated ion.
D)use of P segments to form an ion selectivity filter.

Question

Quizplus · Accepted Answer

Ion channels achieve selectivity through mechanisms such as divergent evolution from a single type of channel protein, low activation energy for selective passage of the dehydrated ion, and the use of P segments to form an ion selectivity filter. The concept of evolving from distinct and different parent proteins does not directly contribute to the selectivity in transport of ion channels.
