The rough er is the site of synthesis of many different classes of membrane protein. some of these proteins remain in the er, whereas others are sorted to compartments such as the golgi apparatus, lysosomes, and the plasma membrane. one measure of the difficulty of the sorting problem is the degree of "purification" that must be achieved during transport from the er. are proteins bound for the plasma membrane common or rare among all er membrane proteins? a few simple considerations allow one to answer this question. in a typical growing cell that is dividing once every 24 hours, the equivalent of one new plasma membrane must transit the er every day. if the er membrane is 20 times the area of a plasma membrane, what is the ratio of plasma membrane proteins to other membrane proteins in the er? (assume that all proteins on their way to the plasma membrane remain in the er for 30 minutes on average before exiting, and that the ratio of proteins to lipids in the er and plasma membranes is the same.) dumb this down

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i. e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
