- How does a cell maintain theright amount of every component(organelles, molecules), and how doesit change these amounts as needed(for example, to greatly expand theendoplasmic reticulum when the cellneeds to produce large amounts ofsecreted proteins)?The cell membranes of mammalian red blood cells are permeableto urea. If red blood cells are dropped into a solution of urea thatis identical in osmotic pressure (isosmotic) to the cytoplasm ofthe cells, although the cells do not swell and burst as quickly aswhen they are dropped simply into pure water, they eventuallyswell and burst. Explain. Also discuss how you would designa solution into which red cells could be placed without everswelling. (Hint: Think about whether urea will stay on theoutside of the cells and the implications for osmotic pressures.)Given that extracellular matrixmolecules have the ability to presentordered arrays of signals to cells,might the exact spatial relationshipsbetween such signals carry a messagebeyond that of the individual signalsthemselves?
