Which is not a role of the cystic fibrosis transmembrane conductance regulator (CFTR)? A Option A: conductor of bicarbonate ions B Option B: facilitative transporter of glucose C Option C: stimulator of activity of a family of epithelial bicarbonate exchangers D Option D: cyclic AMP-regulated chloride channel

"Facilitative transporter of glucose" is not a role of the cystic fibrosis transmembrane conductance regulator (CFTR).

Option: B

Explanation:

A protein and chloride pathway of membrane, in vertebrates encoded with the CFTR gene is understood as "Cystic fibrosis transmembrane conductance regulator (CFTR)". The CFTR gene codes for an ABC-class transporter ion channel protein that conducts chloride ions through epithelial membranes of cells.

The protein helps to keep the salt and water equilibrium on many surfaces in the body, including the lung surface. When the protein doesn't work properly, chloride — a salt part — gets trapped in cells.

i'm sorry, but can you list the answers? i cannot with something i don't know the answers to
