Cystic fibrosis patients lack a gene that codes for a transmembrane carrier of:
Correct answer: A. Cl- ions
- A. Cl- ions
- B. Na+ ions
- C. K+ ions
- D. Ca2+ ions
Explanation
This is the correct answer. Cystic fibrosis (CF) is a genetic disorder caused by mutations in the gene that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This protein is responsible for regulating the flow of chloride (Cl-) ions across the cell membranes of various organs, including the lungs, pancreas, and intestines. In CF patients, mutations in the CFTR gene disrupt the normal functioning of the CFTR protein, leading to an imbalance of salt and water in these organs. This imbalance results in the thick, sticky mucus characteristic of CF, which can cause respiratory problems, digestive issues, and other complications
