LIFESCI 7A Chapter Notes - Chapter 5: Hexosaminidase, Cellular Respiration, Chromatin
Document Summary
Controls flow in and out of cell. Allows cells to maintain a constant internal environment. Responsible for binding and adhering to adjacent cells. Membrane components have been shown to shift from one organelle to another. Extensive network of membrane tubules called cisternae. Consists of flattened membranous sacs and small membrane-enclosed vesicles. Receives proteins from er and further modifies them. Concentrates, packages, and sorts proteins before they are sent to destination. Made in rough er shipped to golgi apparatus. Breakdown of food & foreign material brought into cell by phagocytosis. Sites where digestion of spent cellular components occurs (autophagy) Lipid accumulate in lysosomes of nerve cells in brain. Lack normal synthesis of hexosaminidase a (enzyme) Once proteins lose shape and function (expire) Carried by other proteins to a proteasome. Double layered nuclear membrane that contains nuclear pores. Filled w/ fluid called nucleoplam that contains: Once filled, vacuoles may develop turgor pressure (rigid)
