Question

A cell is sitting in a solution containing 100 mM NaCl, and 30 mM Glucose. The inside of the cell contains 90 mM KCl and 30 mM CaCl2.

a) What are the osmolarities of the intracellular and extracellular solutions?
b) Predict what will happen to the cell, and explain your rationale.

Answer 1

(a)

Extracellular= 0.230 osmols

Intracellular=0.270 osmols

(b)

As concentration of intracellular fluid is higher than extracellular fluid,solvent enters into the cell until the concentration inside and outside are Equal during this,the cell will become swallow.
