Alrighty.
00:02
So this is all about membrane structures and functions and how molecules move in and out of cells.
00:15
And the question at hand is about what happens in a hypertonic solution.
00:20
So there's really two kind of main things, right? so we have our hypotonic and hypertonic.
00:38
And so if this little red guy is the cell, there's going to be different concentration gradients, right? so in the case where it's hypotonic, there's more of the solute in the cell than on outside of it.
01:13
And for hypertonic, the opposite is true.
01:16
So there's going to be more on the outside than on the inside.
01:22
Okay, so then what happens with the cell? well, the cell wants to make equilibrium, and it's going to do that by moving water either in or out of the cell.
01:32
Okay, so when it's hypotonic, in order to get the concentration inside the cell to match the outside of the cell, we need more water in the cell, so to dilute it...
