Passive transport Gracelyn Sims B4
00:07
Passive transport requires no energy and moves from high to low concentrations
00:24
There are three types of passive transport: Simple,Facilitated, and Osmosis
00:37
Simple Diffusion is where the molecules move from high to low. Bacteria uses simple diffusion
01:03
Chapter 5
01:45
Facilitated Diffusion uses proteins to move from high to low. Cells such as carbohydrates use this.
02:15
Chapter 7
03:13
osmosis is the movement of molecules from a solution of high water molecules to low water molecules
03:34
Chapter 9
04:20
Molecules that use simple are oxygen,carbon dioxide and ethanol. Facilitated:glucose, ions
05:03
As I showed passive transport requires no energy and has three different types

Okay today for my presentation I have chosen passive transport.
00:07 - 00:14
So passive transport in my opinion is the simplest, out
00:14 - 00:15
of all the different types of cell transport.
00:16 - 00:21
And basically passive transport requires no energy and moves from
00:22 - 00:23
a high to low concentration.
00:27 - 00:29
So there are three different types of passive transfer.
00:30 - 00:32
Simple facilitated and osmosis.
00:33 - 00:36
And I'm fixing to show you describe each one of
00:37 - 00:37
them and show you how they work.
00:39 - 00:42
So the first one we have is simple diffusion.
00:43 - 00:47
Simple diffusion is where the molecules are moving from a
00:47 - 00:48
high to low.
00:49 - 00:50
That's as simple as it is.
00:50 - 00:51
You know, it's as simple as that of all three
00:52 - 00:53
in my opinion.
00:54 - 01:00
Um And so one cell that uses simple diffusion is
01:01 - 01:07
bacteria. So in this picture I must show you this
01:08 - 01:09
picture is just showing you simple diffusion.
01:09 - 01:12
So as you see the molecules, the top they're all
01:12 - 01:15
very densely packed and then the extra cellular few it
01:15 - 01:20
fluid. So basically they're going to they're trying to get
01:20 - 01:23
to the cytoplasm which is has a lower concentration.
01:24 - 01:27
So to do that they have to they started at
01:27 - 01:30
the top and they go through the lipid bi layer
01:30 - 01:32
which is also known as the plasma membrane.
01:34 - 01:37
So they go through there and then they get put
01:38 - 01:41
in the lower concentration inside a place.
01:41 - 01:43
Um So that's basically how simple diffusion works.
01:43 - 01:45
Not too complicated and pretty easy.
01:47 - 01:52
Next we have facilitated diffusion which is a little like
01:53 - 01:58
um simple, just mm more, not too much more.
01:59 - 01:59
Just different.
02:00 - 02:03
So facilitated diffusion uses proteins to move from how to
02:04 - 02:09
love. So for example, one um cell that uses carbon
02:09 - 02:13
that he says uh facilitated diffusion is carbohydrates.
02:16 - 02:21
So in this picture um it's showing the ion channels
02:21 - 02:27
and islands are actually another thing that uh use facilitated
02:28 - 02:31
diffusion. But so as you see in the cell membrane
02:32 - 02:35
there are these big old green things which are the
02:35 - 02:38
carrier proteins, they're acting like carrier proteins.
02:38 - 02:43
And they're just showing how at the top and the
02:43 - 02:46
extra cellular space there's a bunch of molecules and they're
02:46 - 02:50
going in uh the carrier proteins that carry proteins just
02:51 - 02:53
transport molecules in and out of the cell.
02:54 - 03:01
So basically the um molecules are trying to go from
03:02 - 03:04
higher to lower and do that.
03:04 - 03:07
They have to go through the carrier proteins to get
03:07 - 03:10
into the intracellular space which is where the lower concentration
03:10 - 03:11
is found.
03:11 - 03:13
So that is facilitated diffusion.
03:17 - 03:18
The next one we have is osmosis.
03:19 - 03:20
Which is the last one.
03:21 - 03:28
And basically osmosis uses is the movement of molecules from
03:28 - 03:31
a solution of high water molecules too low water molecules.
03:32 - 03:37
So the only difference is it uses water molecules and
03:38 - 03:41
an example of osmosis is red blood cells.
03:41 - 03:50
They actually use osmosis in here on the lift, you
03:51 - 03:57
can see that we have the modules and they are
03:58 - 03:58
densely packed.
04:00 - 04:03
And so as you see the arrow points the next
04:03 - 04:10
one, they moved through the lipid bi lair to the
04:12 - 04:13
other side.
04:13 - 04:15
And so now they're not as densely packed.
04:16 - 04:17
They moved from a higher to lower, contract.
04:18 - 04:20
And that's basically what all these are.
04:22 - 04:24
They're just moving from higher.
04:24 - 04:26
Lower. They just do it differently.
04:27 - 04:34
And so some here's some more examples um for the
04:34 - 04:34
different types.
04:35 - 04:40
So some more that use simple our auction carbon dioxide
04:41 - 04:43
and ethanol, which I thought those were pretty cool, you
04:43 - 04:46
know? And then something some things that you use facilitated
04:47 - 04:56
our glucose ions, amino acids, those all use facilitated some.
04:59 - 05:01
And so there's plenty more of each.
05:01 - 05:03
Those are just the ones that I happened to come
05:03 - 05:09
across. Okay, so basically what I was trying to show
05:09 - 05:13
you is that passive transport is the way cells move
05:15 - 05:17
throughout the way molecules move throughout the cell.
05:18 - 05:21
They just they can use any of the types depending
05:22 - 05:22
on what they are.
05:25 - 05:31
And they all work very closely.
05:32 - 05:34
They're just each have their own little parts.
05:35 - 05:37
So that is what I've did.
05:37 - 05:38
