Consisder simple cell model that consists of cytoplasm surrounded by cel membrane. The cell's initial volume is 3nL and contains .3M protien and .1M Ca++. This cell is immersed in a .2M urea bah. Unlike Ca++ and Cl-, urea an cross the membrane barrier.
(a) What occurs as the cell reaches equilibrium?
(b) What is the final osmolarity of the cell and the solution?
(c) What is the final cell volum.
