The statement that is false regarding the relationship between the CFTR protein in a cystic fibrosis patient and chloride ions, water movement, and mucous consistency is B) The CFTR protein forms a working chloride ion channel.
What is the relationship?
In cystic fibrosis (CF), the CFTR protein is dysfunctional, resulting in a non-functional chloride ion channel. The mutated CFTR fails to regulate chloride ion movement properly, leading to impaired water movement across cell membranes.
So, Contrary to statement B, the CFTR protein does not form a functional chloride ion channel, causing dysregulation of chloride and water movement, ultimately affecting mucous consistency and leading to clinical manifestations of cystic fibrosis.

Which statement is false regarding the relationship between the CFTR protein in a cystic fibrosis patient and chloride ions, water movement, and mucous consistency?
A) Chloride ions enter and remain in the cell.
B) The CFTR protein forms a working chloride ion channel.
C) Water molecules enter the cell for dilution purposes.
D) The dehydrated mucosal lining traps bacteria and particulates.
