Question

Quizplus · Accepted Answer

Cystic fibrosis is caused by a defective gene that produces a nonfunctional protein called cystic fibrosis transmembrane conductance regulator (CFTR). This protein is responsible for regulating the transportation of sodium and chloride ions across cell membranes. When the CFTR protein is not functioning properly, it results in the production of thick, sticky mucus in various organs, including the lungs, pancreas, and digestive system. This mucus buildup can lead to severe respiratory infections and digestive problems.
