Hi there.
00:03
This question is about a red blood cell and which solution would cause it to go, to undergo hemolysis.
00:17
And hemolysis is when the red blood cell ruptures or breaks open.
00:27
Okay, so this is going to happen when we get too much water flowing into the cell because the cell will just keep blowing up like a balloon until it eventually lises or breaks open.
00:45
So we need to think about the concentration of each of these solutions.
00:50
The inside of a red blood cell is usually about 0 .9 % in dissolved solutes.
01:00
So 0 .9%.
01:02
So if we were to put this in a 5 % solution, the 5 % would be hypertonic to the cell.
01:14
And water would flow out of the cell.
01:18
Similarly, if we have a 5 % nacl solution, both of these solutions are more concentrated in solute than the 0 .9 % inside the cell.
01:35
So again, we have a hypertonic solution and water would flow out.
01:40
If we had a 0 .9 % nacl solution, this would be isotonic...
