Question

Quizplus · Accepted Answer

Cystic fibrosis is a genetic disease that affects the transport of chloride ions across cell membrane. In individuals with cystic fibrosis, the chloride ions are not properly transported out of the cells, leading to thick, sticky mucus that clogs the airways and other organs such as pancreas and liver. The malfunction in chloride ion transport is caused by a defective gene that codes for the CFTR (cystic fibrosis transmembrane conductance regulator) protein, which normally helps regulate chloride and other ion transport across cell membranes.
