The Cystic Fibrosis Gene (CFTR)codes for a Protein That Is

Question

The cystic fibrosis gene (CFTR)codes for a protein that is essential for
A)secretion of mucus.
B)ion transport across membranes.
C)transport of oxygen in red blood cells.
D)metabolism of certain amino acids.
E)processing of gangliosides.

Accepted Answer

The CFTR gene codes for a protein that functions as an ion channel, facilitating the transport of chloride ions across cell membranes. This has a significant impact on the function of multiple organs, including the lungs, pancreas, and digestive system. In individuals with cystic fibrosis, mutations in the CFTR gene lead to the production of a non-functional or reduced-function protein, resulting in impaired ion transport and a range of associated symptoms.
