- Why is the Donnan membrane phenomenon important for the homeostasis of the cell?Why does a eukaryotic cell need both membranous organelles and fibrous cytoskeletal components? Justify your answer1) whether the statement is correct or incorrect and 2) the reasoning for your answer. Your answer should demonstrate your understanding of the physiological concepts underlying the statement and be professionally written. Assume a cell with the following properties: [Na]out = 120 mM; [Na]in = 12 mM [K]out = 5 mM; [K]in = 125 mM Membrane is permeable only to Na+ and K+ If the plasma membrane of the cell becomes more permeable to Na+, both influx of Na+ into the cell and the Na+ equilibrium potential will increase.
