Diffusion | Membranes and transport | Biology | Khan Academy

Understanding how particles passively diffuse down their concentration gradient.

Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.

Honestly this guy is extremely helpful!

[greentoad]

I’ve been trying to find a video that tells the right thing and this is just the right one!

[mahinalam]

Wow! I had no idea diffusion actually occurs due to the probability of the random movement of molecules (in a concentration gradeint)
Thanks! Can we get a video on 'Osmosis' now?

[saminakhalid]

Oh god plz pray for me my bio exam is the day after tomorrow

[fakehatehseen]

What if you had more number of molecules on the right hand than on the left.Will it still be diffusion if molecules move from higher concentration to lower concentration, no matter what the direction is left or right.??

[kevinkim]

I thought of it as like a subway car as if it is packed you obviously will move to a car where there are less people. If that helps anybody?

[ineedyou]

Thank you so much, this video really helped me with my science project. ❤

[harshi]

This video helps me alot Thanks Khan Academy

[u.v.s.]

You do notice that the direction arrow of the concentration gradient is wrong?

[winpattanaphol]

Really easy to understand! Very helpful with my study session :D

[Nichud]

thank u its helpful for my science homework😎

[georgeashby]

If ur watching this coz u don’t understand diffusion in revision before ur exam ur going to fail

[tobifadeyi]

Instead of 'I got, I my DNA' it's 'I got, I got 4 molecules inside my cup of glass'

[rubberband]

Finally, A person that is speaking english and not science

[iamthestrongest]

Why, just why... (Write the rest of the sentence and comment)

+mahin alam I think there is already a video on that on Khanacademy.
