Cystic fibrosis is a disease caused by a defective gene on chromosome #7 in humans. This gene codes for a transport molecule (CFTR = cystic fibrosis transmembrane receptor) that is found in the cell membrane of cells and is involved with movement of water and chloride ions across the plasma membrane. These transporters are typically found in tissues lining ducts, including the breathing passages of the lungs and the organs that are involved with food digestion and absorption. People with cystic fibrosis often suffer from a lack of oxygen. Oxygen is required by what cell organelle?
