Asbestos is a material that was once used extensively in construction. One risk from working in a building that contains asbestos is the development of asbestosis caused by the inhalation of asbestos fibers. Cells will take up asbestos by phagoctytosis, but are not able to break it down. As a result, asbestos fibers accumulate in which organelle? Golgi apparatus nucleus peroxisomes lysosomes

Organelles and Cystic Fibrosis A plasma membrane transport protein called CFTR moves chloride ions out of cells lining cavities and ducts of the lungs, liver, pancreas, intestines, and reproductive system. Water that follows the ions creates a thin film that allows mucus to slide easily through these structures. People with cystic fibrosis (CF) have too few copies of the CFTR protein in the plasma membranes of their cells. Not enough chloride ions leave the cells, and so not enough water leaves them either. The result is thick, dry mucus that clogs the airways to the lungs and other passages. Symptoms include difficulty breathing and chronic lung infections. In 2000, researchers tracked the cellular location of the CFTR protein as it was being produced in cells from people with CF (Figure 3.13). Figure 3.13 Cellular location of the CFTR protein. Graph compares the amounts of CFTR protein found in endoplasmic reticulum, vesicles traveling from ER to Golgi, and Golgi bodies in CF cells and normal cells. In which organelle is the amount of CFTR protein most similar in both types of cells?

Fresh out of college, Maria has her first job teaching school. When she goes for a pre-employment chest X-ray required by the school district, the technician places a lead-lined apron over her abdomen but not over any other part of Marias body. The apron prevents electromagnetic radiation from penetrating into the protected body area. What cells is the lead shield designed to protect, and why?
