Passive Transport

[Jnimgaon]

hey ppl from ms. shoop's class.



[mrJust2468]

My biology teacher made me watch this

[TNC408]

I hate exams 

[cyphertek]

This might be the correct classification for the leakage channels found on axons in neurons.

[SilverSalt7]

0:18 whether the direction is out or in XDXDXD

[xxmrrickxx]

This is not simple diffusion, it is facilitated diffusion because it involves membrane channel proteins to allow hydrophilic substances to pass through.

Only small, lipid soluble substances, such as dissolved oxygen and carbon dioxide, can pass directly through the phospholipid bilayer through simple diffusion (without channel proteins)

We have a test on diffusion, osmosis, etc. in our 7th grade science class tomorrow...

This video just helped me confirm I know the stuff :)

[madhouse47]

cool

[PINKMEE143]

how can i download this one?

[JIIHD]

Energy is still being redirected and utilized its just simply aided by affinities WHICH suggests a power source of what magnetism or gravity?

[JIIHD]

So can this passive transport be a model for energy conservation and or production?

[chaders89]

ty this help me in science

[rangeyo]

so basically passive transport only requires the channel proteins, and the phospholipid bilayer is not used?

[AUdave11]

not from what ive learned. It's a bit confusing how all youtube videos show passive, active and facilitated as THE THREE WAYS. There are more like 5: 1.)passive diffusion 2.) channels and pores 3.) facilitated diffusion 4.) active primary and 5.)active secondary. Passive diffusion is the only one that does NOT require a protein carrier. only the active transports move UP a gradient, and primary is based on energy used (light, ATP, ect.) and secondary is ion gradient based. hope this helps!!

[rangeyo]

k thanks :)

[MrWonderful5]

Nonono it's still used of course.. But the other passive proteins for channel ones are used mainly for bigger molecules..

Ones that can't really fit through the tiny spaces of the phospholipids bilayer. It's still passive though, just matters on the size.

[summersgrey]

Yes, from what I've learned, facilitated diffusion is under passive transport, cuz it doesn't require energy, only it is facilitated by carrier protein down the concentration gradient

[hebatakaku]

osmosis.

the best passive transport to me..

[maylinreese]

passive transport.

-simple diffusion.

-facilitated diffusion.

-osmosis.

[edik1990xx]

im from germany can sb tell me whats the word at 0:17 and its meaning?

naturally diffuse from the side with more .....

to the side with less...... ..?

[DrewPacker1]

This is essentially simple diffusion.

[urockit2011]

yeah that's what i thought

[SpellMePlz]

A solute is a substance (usually in lesser] amount) dissolved in another substance

[Ludmichka]

...more solute

[mitchcookskate]

solute.. basically its like concentraition. because its passive, eg diffusion, so the solutes diffuse through teh cell membrane from aprts where there is high concentration to parts where it is low. this is a passive process because it is movign down the concentration gradient.Solutes are jus like salt molecules ay i think, hope it helps

[adamengine81]

more concentration moving to less concentration

[SjaQ1986]

solute: aufgelöste Stoffe

[ksaGRL]

thank u sooo much

it's easier to understand it from this video

[drsakhr]

Passaive transport is triggered by concentration gradient and could be :

- Simple diffusion .

- Facilitated diffusion by channel proteins and carrier proteins .

Thanks

[Kitsunetaisen]

jajajajajajajajajajajajajajaja­ja

[sapita1]

love this video

[riv864]

where can i get the full version of these videos ? or does anyone know the name of the video?

[casanovadragos]

wow...great video..I'm in ninth grade and I love these things...

[obertoelson]

best video i have ever seen

its the best video i have ever seen

i love biology

[joseluis8585]

thank u very much it helped me alot

[marie4858]

it has helped me out greatly

[yatesjl35]

it's amazing how much life is going on is me. lol.

[angieeucaa]

love the citology videos
