Cystic fibrosis is a genetic disease that leads to the production of excessive, thick mucus in the respiratory tract, causing frequent and serious respiratory infections. The defect is due to the production of a faulty membrane protein for the transport of the chloride ion. The protein exists in membranes, but it doesn't function normally. Based on this scenario, what is occurring at the molecular level in a person with cystic fibrosis?

Question

Quizplus · Accepted Answer

The faulty protein in cystic fibrosis is the CFTR protein, which is a chloride channel protein. It is responsible for the transport of chloride ions across cell membranes, and its malfunction leads to the symptoms of cystic fibrosis.
