A sac made from dialysis tubing contains a solution of 4% NaCl and 16% glucose. It is suspended in a beaker containing a solution with the following composition: 10% NaCl, 16% glucose, and 40% albumin (a protein found in blood plasma). Assume that the sac is permeable to all substances except the albumin. (4 marks) Hint: Draw a diagram so you can picture how this is set up, then think about the difference between the concentrations. Select the best answer from the choices, A-D, to predict the net movement of NaCl, glucose, albumin, and water. A. Move out of the sac. B. Remain outside of the sac. C. Move into the sac. D. Remain in the sac.

00:01 So, which is a cause you're going to solve it together.

00:09 It's an othmosis diffusion process.

00:14 It's an osmosis process since you have a tubing, dialysis tubing.

00:20 So right away i'm going to draw the dialysis tubing, similar to a tube.

00:26 Then we have a membrane sac.

00:29 A membrane sac could be something like that.

00:33 And then inside this membrane sack we have 4 % sodium chloride, we have 16 % glucose.

00:49 Then out of this membrane we have 10 % sodium chloride.

01:02 We have 16 % glucose, 16 % glucose, right? so if you have that percentage, then we have added elberon.

01:30 Algarbamine, we have agarbamine, it is also 40 % agalbumen outside.

01:41 Then remember we have semi -permable membrane sac around this region, which means going to selectively allow substances to move in and out of this sack.

01:58 So let's look at the concentration of these substances.

02:08 We look at the concentration of these substances in and out.

02:15 Sodom chloride is 4 % in, out is 10%.

02:26 Glucose is 16 % in, 16 % out.

02:36 Further, ergo bimen.

02:43 You don't have it in, but you have it out, 40%.

02:45 Okay, then you have water.

02:54 Water in, we're not given concentration and water out.

03:01 We're not given any concentration here.

03:04 So, osmosis is a process by which substances move from the region of high concentration.

03:11 Osmosis.

03:16 Substances move from the region of high concentration to the region of low concentration.
