Gaucher disease is the most common of lipid storage diseases in humans. It is caused by a deficiency of an enzyme necessary for lipid metabolism
This leads to a collection of fatty material in organs of the body including the spleen, liver, kidneys, lungs, brain, and bone marrow. Using your knowledge of the structure of eukaryotic cells, identify the statement below that best explains how internal membranes and the organelles of cells would be involved in Gaucher disease. A) The mitochondria are most likely defective and do not produce adequate amounts of ATP needed for cellular respiration. B) The rough endoplasmic reticulum contains too many ribosomes which results in an overproduction of the enzyme involved in carbohydrate catalysis. C) The lysosomes lack sufficient amounts of enzymes necessary for the metabolism of lipids. D) The Golgi apparatus produces vesicles with faulty membranes that leak their contents into the cytoplasm of the cell.
