Explanation:

Cystic fibrosis is caused by mutations in the CFTR gene. The CFTR protein is a chloride channel that regulates the movement of salt and water in and out of cells. When the CFTR protein is not functioning properly, it leads to the production of thick, sticky mucus that can block the lungs and airways, as well as other organs.

Answer:

salt and water movement in cells
