It has something that is terribly important it has what's called an active and permeable membrane around the edge.

Part of the chamber opens to a differentially permeable membrane that lets water molecules through, but not the solute particles.

Rather, the main let me underline this the main reason is the concentration gradients established by the pump in combination with the fact that the resting cell membrane is highly permeable to potassium and only slightly permeable to sodium.

And now what he's saying is that the main cause of the potential difference isn't this ratio, it's the fact that the membrane is highly permeable to potassium.

So this is very permeable.

And then you have that little basement membrane like a thin line of membrane called the basement membrane

I knew that line was movable, and it was permeable.

(a) Aquifer means a permeable water bearing geological formation underlain by a less permeable layer and the water contained in the saturated zone of the formation

That's the membrane.

It has an outer membrane and an inner membrane just like that.

That's its outer membrane.

The membrane is translucent.

That's its outer membrane.

These are membrane bound.

The thylakoid has a membrane.

It has an outer membrane.

It has an inner membrane.

Let me draw the membrane.

And in that case it was in the mitochondria, here the membrane is the thylakoid membrane.

And so basically what you're going to have is this membrane. So we've got a membrane

And then this side is normally referred to the basal lateral side, or this membrane, if you view this as a membrane, this would be the basolateral membrane.

A permeable geological formation has pores that permit liquids or gases to pass through.

Offshore Membrane Enclosures for Growing Algae.

And this membrane is especially important.

This is a phospobilipid layer membrane.

A proton pump is an integral membrane protein that is capable of moving protons across a biological membrane.

So these little vesicles, they're docked to the presynpatic membrane or to this axon terminal membrane right there.

The sinus cavity is lined with a membrane called the Sniderian membrane, which may or may not be perforated.

So on this membrane you have these proteins and these complexes of proteins and molecules that span this membrane.

That's going to be ATP, in the form of ATP. It basically has a folded membrane inside a membrane.

So these have a super thin membrane.

And then you have your outer membrane.

literally snared the vesicles to this membrane.

Around 50 per cent of the population, especially the urban population, is connected to the sewage system, while the rural population in most cases dispose of liquid waste by depositing it in permeable or semi permeable tanks.

The reservoir must also be permeable so that the hydrocarbons will flow to surface during production.

The most commonly used membrane is Nafion by DuPont, which relies on liquid water humidification of the membrane to transport protons.

And let me zoom in on the membrane.

It's going to be surrounded by a membrane.

They are subunits, membrane bound subunits of cells.

So we're zoomed in on the thylakoid membrane.

So this is the thylakoid membrane right there.

I'm going to zoom in on its membrane.

So while it is true that the normal stoichiometry of the pump does have a slight negative influence on the membrane potential that's just the membrane potential, the voltage across the membrane the imbalance in the pump stoichiometry is not the main reason for the large negative membrane potential of the cell.

There is no appearance of a membrane about them.

So seawater reverse osmosis is a membrane filtration technology.
