Cystic fibrosis is a genetic disease in humans in which the CFTR protein, which functions as a chloride ion channel, is missing or nonfunctional in cell membranes.

The CFTR protein belongs to what category of membrane proteins?

A) gap junctions

B) aquaporins

C) electrogenic ion pumps

D) cotransporters

E) hydrophilic channels

The correct answer is - option C. electrogenic ion pumps

Explanation:

The CFTR protein which acts as the chloride ion Channel this Chanel is belongs to the Electrogenic pumps. These are also is categorize as the ABC Protein channel.

Electrogenic pumps are primary active transporters that hydrolyzes the ATP and the produced energy is used to transfer ions (cl ion in this case) across the membrane to generate the gradient across the membranes.

Thus, the correct answer is - option C. electrogenic ion pumps.
