Compound Sodium Lactate is isotonic solution. this mean that it  a. reduces movement of sodium across the membrane  b.prevent movement of water across the semi permerable cell membrane  c. promotes movement of water out of the cell d. facilitates equal movement of water across the semi permerable cell membrane

You have a beaker filled with a solution containing 2M glucose, 4M urea and 1M salt.Suspended in the solution is a cell that containing a solution of 1M glucose, 8M urea and 3Msalt. The membrane of the cell is permeable to glucose and salt but not urea. Answer each of thefollowing questions:a. Where will water move?b. Where will urea move?c. Where will glucose move?d. Where will salt move?e. What will happen to the volume of fluid inside the cell?f. What will happen to the osmolarity of the fluid inside the cell?

The pathway that can move highest rates of sodium ions is: A. Sodium channels B. Sodium pumps-ATPases C. Sodium exchangers D. Sodium diffusion in solution
