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 travel in g from ER to Golgi, and Golgi bodies in CF cells and normal cells. Which organelle contains the least amount of CFTR protein in normal cells? In CF cells?
Put the following structures in order according to the pathway of a secreted protein: a. plasma membrane b. Golgi bodies c. endoplasmic reticulum d. post-Golgi vesicles
Figure 3.13 Why does the cis face of the Golgi not face the plasma membrane?
Integrins are important in cell crawling because they anchor the leading edge of the cell to the surface it is moving over they are receptors for diffusible chemical ligands that determine the direction the cell will move in they cross-link actin filaments to microtubules and intermediate filaments of the cytoskeleton they serve as nucleating sites for polymerization of new actin filaments
which cell structure would play a role in cell migration? phospholipid bilayer peripheral protein serving as an enzyme intercellular joining between two body cells integral protein serving as a carrier
which structure in this figure? endoplasmic reticulum golgi complex O lysosome contains the cell's hereditary information and controls the cell's growth Nuclear Envelope nucleus nucleolus
From the options shown what proteins types/groups would not be present in vesicles budding from the trans-Golgi network? O proteins destined for the plasma membrane O proteins destined for the peroxisomal matrix O proteins destined for the endosome O proteins destined for the lysosome, O proteins secreted by exocytosis
Cell with extensively developed Golgi apparatus is most likely to exhibit which of the following properties Select one: O a. Synthesis of large amount of secretory proteins O b. Actively involved with phagocytic activities O c. Generates a large amount of ATP O d. Secrete a large amount of steroids O e Synthesis of abundant phospholipids
Neurons have long thin processes called axons, structuresspecialized for conducting signals throughout the organism’s nervous system. Some axonal processes can be as long as 2 m—for example, the axons that originate in your spinal cord and terminate in the muscles of your toes. Small membrane-enclosed vesicles carrying materials essential to axonal function move along microtubules of the cytoskeleton, from the cell body to the tips of the axons. If the average velocity of a vesicle is 1 μm/s, how long does it take a vesicle to move from a cell body in the spinal cord to the axonal tip in the toes?
Match each of the following cellular structures with the one function that best describes it. Site where the cell first makes contact with a virus Composed of microtubules, intermediate filaments, and microfilaments Site of cellular respiration, which generates ATP Organelle that "reads" RNA to create a protein from amino acids Site where proteins are modified into glycoproteins Site where proteins complete their modifications and are transported to other locations, inside or outside the cell General membrane-bound transport structure A vesicle involved in the process of endocytosis that becomes increasingly acidic Contains enzymes for intracellular digestion of malfunctioning organelles or ingested pathogens Location of genetic material 1. ribosome 2. nucleus 3. lysosome 4. 5. 6. Golgi complex 8. rough ER mitochondrion 7. vesicle cytoskeleton 9. plasma membrane 10. endosome
Which of these organelles is directly involved in the synthesis, editing, or modification of cell components? Mark all that apply. Group of answer choices actin (8 nm) microfilaments cilia flagella free ribosomes Golgi complex (Golgi apparatus) intermediate (10 nm) filaments lysosomes microtubules (25 nm) peroxisomes proteasomes rough endoplasmic reticulum smooth endoplasmic reticulum spliceosomes
Part D - The Golgi Apparatus Label the diagram below by dragging and dropping the descriptions. Each label will be used only once. ▸ View Available Hint(s) ‒‒‒‒‒‒ Transport vesicles arriving from the endoplasmic reticulum Forming (cis) face Cisternae Maturing (trans) face Secretory vesicle departing for the plasmalemma Plasmalemma Reset Help Lysosome containing digestive enzymes
