Okay, when i'm going to answer this question, let's talk about osmosis.
00:02
Okay, osmosis is a type of simple diffusion.
00:07
It means there is no transporters here.
00:10
And substances are going to move across a membrane, a membrane due to gradient, okay, without using transporters.
00:19
For example, if this is your cell membrane, this is an extracellular matrix and this is an intracellular.
00:26
Then if you have, well, omnostic also refers to, water and gases.
00:35
Okay, so first of all, this membrane has to be a semi -permeable membrane.
00:43
It means it's a membrane that is permeable to specific substances and it is not permeable to other substances, okay? and there should be also a gradient.
00:53
For example, let's suppose here we have high levels of oxygen and here we have low levels of oxygen.
01:00
So because of this gradient, remember that a gradient is going to make a substance move from a compartment with high concentrations to a compartment with low concentration.
01:09
So this is going to be the direction of movement...
