Never in my life understood the process of PASSIVE TRANSPORT. I read my book over 50 times and still didn't understand . once i found this video online i took notes and organize it. WOW ITS AMAZING I UNDERSTOOD FOR THE FIRST TIME CELL MEMBRANE PASSIVE TRANSPORT... who ever post these video is an angel
That's thing. I think that the cell's energetic reactions result in heat being released in the cell. This heat aids in the Brownian motion. So the cell is helping in the movement of Brownian motion indirectly
@nigandmad Because it's the opposite charge of the net charge inside the cell, so it's pushing it away. Like trying to push the negative sides of a battery together it just doesn't work.
You are correct. Diffusion depends entirely on kinetic energy. I wouldn't say it's exclusively "the cell's energy" however. All atoms (that are not at absolute zero temperature) posses kinetic energy. In liquids and gases these atoms are constantly zooming around super fast! The rate of simple diffusion is directly influenced by the temperature of the molecules.
anyone can xplain wht a polar molecule is? and y does the plasma membrane not allow polar molecules, ions, and hydrophillic molecules to diffuse through it\?
There are many factors that affect the rate that which molecules move across the membrane, temp being one of them. However it could be 60 degrees on each side and the molecules have an equal conc. gradient, thus no movement across the membrane, but yes the molecules are still moving independently due to the temperature (as do all molecules that move dependent on temperature, e.g. boiling water). The important factor to understand here though is that the cell is not providing energy the energy.
yea, active transport has its name because it uses "ATP" to to get ions or etc in or out. correct me if im wrong, but thats what i learnt in biology :)
we are truly wonderfully and fearfully made; whoever believes in evolution must reason that it took billions (or trillions) of years for these kinds of processes to take place
I hate how they say 'passive transport' requires no energy from the cell. I really doubt that. I doubt that the cell's heat energy has nothing to do with the diffusion of the molecules. I think that the heat of the cell allows the chemicals to move, and thus undergo diffusion. i don't think diffusion would have occurred in a cell if the cell did not provide heat energy.
this english is too difficult for me to understand :( and in german there's nothing about this bullshit, what about we're going to write a test tomorrow..

Cool...Explained very clearly....better than my Biology teacher
This is so understandable, basic, to the point just what I needed. Thanks
Thanks for the simplicity, clarity and explanation.
thank you for posting this!!
simplifies what our textbooks don't!. Love your videos
Thanks for posting this!
There's a reason these videos exist, and it's not to "bore"
Excellent explanation. Thank you big time!
good voice for this... great rendition... u didnt let my mind wander :)
youre a doll for posting this
wow
I saw the upload date and the quality and thought it is not worth it but no
this is better than my biology doctcor
Thank you! But what about osmosis?
Showing this in my class tomorrow! :D
wonderful video, it really helped me. Thanks
Liked this explanation helped me a lot thank u for your videos
this rescued my presentation in biology, thanks! :D
it has been a long time, nearly a decade
my confusion btwn carrier proteins and channels is solved..thnks a lot.
Omg I'm in class right now after we watched the vid~_~ lol
best yet
Learned at least three new things :)
@nigandmad A polar molecule is not neccessarily charged but has atleast a polar head group so X-OH is polar.
That's thing. I think that the cell's energetic reactions result in heat being released in the cell. This heat aids in the Brownian motion. So the cell is helping in the movement of Brownian motion indirectly
thankx for increese my knowledge
حلو كتير شكرا Thanks :D
wonderfull animations
Good video.
i have to take a biology test on this today thanks for vid
Yes, you may use this video.
@nigandmad Because it's the opposite charge of the net charge inside the cell, so it's pushing it away. Like trying to push the negative sides of a battery together it just doesn't work.
Nice Video That You Share , So Very Nice Thanks You Segment from the program Cell Membranes: The Boundaries of Life.
@greatpacificmedia would you have the active transport bit on this??? please?????

i agree!
anyone can xplain wht a polar molecule is? and y does the plasma membrane not allow polar molecules, ions, and hydrophillic molecules to diffuse through it\?
how the structure of the cell membrane relates to active and passive transport?
love the music in the end...
Your keen observation skills must have missed the banner that told you where to purchase the full video.

is the cell membrance really selectively permeable?i saw everything dropped pass through the membrane
Hey Can you Make a Paragraph of Active tans.. And Passive Tans
yea, active transport has its name because it uses "ATP" to to get ions or etc in or out. correct me if im wrong, but thats what i learnt in biology :)
LIKE & Thanks

wasn't facilitated diffusion is in the active transport ???
Me too!

I think that the heat of the cell allows the chemicals to move, and thus undergo diffusion. i don't think diffusion would have occurred in a cell if the cell did not provide heat energy.
facilitated diffusion doesn't use ATP whereas active transport does..
Been a while hey
if i get an a on my test 2morro on passive and active transport i will like, favorite this video and subscribe
I want James Cameron to film an epic, 3D movie about the cell.
@cjsuljic no i got a c :(
@greatpacificmedia You're*
Bio test tomorrow...Im fucked!
i have a biology test tomorrow D:
i din,t know there were different types of difussion know i know ..... hi mr if you see my comment
1st comment in 4 years
Bitch please I am in the exam room watching this from my iPhone
fucking hell
Carlos Melendez Ha ha haaaaaaaaaaaaaaaaa I know right? Good
Lord!!!!!!
So old comments
2nd comment in 3 years.
Im still fucking confuses
Hawker anyone?
it would be a lot helpful if whoevers' talking, wouldn't do so WAY TOO FAST.
bitch please I have biology test 2 hours from now
this is creepy
this english is too difficult for me to understand :( and in german there's nothing about this bullshit, what about we're going to write a test tomorrow..
How rude...
Ima Tell you know that he doesnt explain Sh*t its all complicated.
