waste product of metabolism, to the lungs, where it is excreted (5) The shape of a red blood cell is biconcaved which helps the cell function. The shape of the red blood cell is important because it allows oxygen exchange at a steady rate over a large area. The function of a nerve cell in our body is to relay information as electrical signals fromt the periphery to central nervous system. (6) The shape of a nerve cell is composed of tiny branches that are called dendords which will branch off into smaller ones called dentrites. The nerve cell having this shape helps it function by having passageways to send electrical signals throughout the bod y. (7) 4. Choose from one of the following diseases/disorders that affects organelles or cellular components. (200-word minimum) Mitochondrial disease Zellweger disorder Lysosomal storage disorders Then, answer the following: ● Name of the disease/disorder that was chosen 2
SC121 Unit 4 Assignment ● Which part of the cell is affected? ● How does this part of the cell normally function? What does it do for the body? ● How does this disease/disorder develop? In other words, how do you get it? ● What are the symptoms? ● What options are available to treat this disease/disorder The Zellweger disorder is a disorder caused by a mutation in any one or more of the 12 different genes that are involved in the creation and proper functions of peroxisomes ( Zellweger syndrome. (n.d.). Peroxisomes are organelles that are found in almost all body cells. Peroxisomes are cell structures that break down toxic substances and synthesize lipids (fatty acids. oils, and waxes) that are necessary for cell function. Peroxisomes are required for normal brain development and function and the formation of myelin ( Zellweger Syndrome Information Page.
