- Transport In Cells: Active Transport | Cells | Biology | FuseSchool
In the first part of this video, we looked at diffusion to move gases and osmosis for the movement of water, from high concentration to low concentration down their concentration gradient. You can watch it here: • Transport in Cells: Di...
Active transport works in the opposite direction; it moves molecules from a low concentration to a high concentration, against the concentration gradient. This is the opposite of diffusion and osmosis. And because it is not the natural direction, energy from is required to make this work.
Active transport is carried out by protein carriers. The protein carriers are within the cell membrane and they have a specific binding site for the exact molecule they are transporting. The substance binds to the protein carrier on the side that it is at low concentration. And using energy from respiration, the protein carrier releases the substance on the other side of the membrane - where it is already at a higher concentration.

No, you are not the only one watching this half an hour before the exam
You just made my life easier!I can sense A+ diffusing into my bio paper
Haha great to hear that!
Did u get it?
😀😂same
that was smooth
damn
I'm only 51 seconds in and you have already explained it better than my teacher! Thank you!
Haha great! Thanks!
Then your teacher sucks I fish the full video and my teacher explain more
My teacher looked at this comment and got annoyed haha
My teacher made us watch this 😂😂
@@shark753 Promote your science teacher and fire your English teacher.
dang this covers about 1 lecture in my class.
also, i love how these videos are short, and right to the point. not too fast, either! :)
Glad you liked it!
"See, you don't really need energy to go down a slide"
Physicists: "So you have chosen death"
exactly...its KINETIC ENERGY...pls. video so good yet i feel attacked. haha
You just made it much better! I was roaming around my room to study active transport! 😂 But finally, you appeared as a last min teacher for me! Thanks loads 😊
Within 2 mins you have made it crystal clear to me
So glad to hear that 🙂
it really be your own teachers. This is so easy to understand. WHY DO THEY MAKE IT SO HARD
this is such a great video! very simple and informative :) thanks
This is a really good video. My PAP BIology teacher teaches, but she speaks a lot, so i dont pick up any information. So thank you so much!
Karina Franklin. Lol. Same problem here 😅😅😀
Lol
it helped me in my exams and i got an B+
Great to hear - well done!
👍🤓✔️
Awesome j!
nice
Wow, this is sooooo much of a better explanation for this subject. My teacher couldn't top this in a million years. I'm gonna get a 9a for sure in my GCSE test now. Thanks a lot!! :-D
Glad we could help!
Omg same. I have my gcses this year
the background music sounds like Amoeba Sister‘s video opening lmaooo
OMG THX SO MUCH. Because I watched a lot of your videos I needed I got the highest grade in science and I might move to top set
Fantastic! Well done 🙌
Your welcome
A big thank you for contrasting and explaining these three!!!!! u made life easier
Most welcome! Glad it helped!
this is great THANK YOU SO MUCH FOR TAKING STRESS OFF MY SHOULDER I THOUGHT I WOULD HAVE TO STAY UP ALL NIGHT FOR THIS
Glad it helped!
Love his voice too. Clear explanation makes me understand better.
Glad to hear that!
This is the best educational channel , it provides us the concept in the best and a quick way . thank you so much to fuse school .
You're most welcome! Happy to help!
Pls no this video teaching me more than what my teacher taught me in 3 months tysm for this it saved my life
You are most welcome! Happy it helped!
I love Active transport
i have a science exam tommorrow!!!
Arnold Aaron how was it?
Arnold Aaron same
Arnold Aaron good luck!
@Shamsa Al-Junaibi that was 8 months ago lol
i have biology plsllsls
great!Thanks
This is so helpful! Thank you so much, I don't have to struggle on my biology exam!
jiminieeee
tmrw I'm having science exam & hope it'll surely help me....thanks 4 the video....
Hope it went well!
Well said
Made it so easy thank you so much you saved my time thank you once again
You’re very welcome 😊 We're always happy to help!
Really good and too easy but if you talk about the isotonic,hypertonic and hypotonic it will be very good
well done!
@fuseschool your videos are just so simple, and brilliant
So nice of you! Thanks!
Very well explained 👍❤️I understood whole concept
Glad to hear it!
Best explanation ever
Wow, thank you!
Thank you, well explained
Glad you liked it
Thanks! This helped a lot😊
Glad it helped!
short video that gives a lot of information and its not boring ……………...…. thanks
Glad you liked it!
beautiful it's really advantageous
Thanks
Very well explained :-)
this was very helpful! thank you!
Glad to hear it!
Thnx for this video, the best explanation so far
Wonderful! Great to hear that 😊
Well made video, thank you!!
Thank you too!
Thank you very much❤️
No problem!
Thanks! This was very informative!
Glad you enjoyed it!
amazing
Thank you for such a great explanation
You're very welcome!
verry nycc explanation .... time saving and knowledge increasing video😊😊
Thanks a lot 😊
You guys are awesome thank you 😊
So nice of you!
THIS IS SO HELPFUL!!!! THANK YOUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :D :D :D :D
ur welcome
Thank you! So nice of you
Good
Excellent Sir... thanku so much sir ❤️❤️
You are most welcome!
Great video, thanks
Thank you!
Good.
Thanks great help
thanks for this great video im much better at biology now
No problem! Always happy to help!
great
please do more vedeos its use full tnks
Great video. Still a little confused on the difference between osmosis and diffusion though. Are they the same except they are used for different substances?
Check this video: ua-cam.com/video/PRi6uHDKeW4/v-deo.html
Awesome explanation
Glad you liked it!
The video is very helpful. However I had trouble looking for it, if newer videos could have the same title for part 1 and 2, or a link to the video that would be very helpful
Noted! Thanks for your feedback!
short and to the point! thanks! my McGraw Hill E-book is fully trash.
Can you name different factors which affect the rate diffusion and how?
thanks
Thank so much i understood much better than I did at school, and it really helped me In my exam
Wonderful to hear!
Very informative video thanks
Glad it was helpful!
OMG You explain it better than my teacher thank you
Happy to help!

Extremely helpful
Glad to hear it!
Hey that's pretty good
good examples man.
Cheers!
Nice and helpful video
Glad to hear that
thanks sir this helped me so much 😀
Most welcome 😊
Well but active transport could also apply on a natural concentration gradient(i.e. From high to low)
Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 😈
Helllloooooo, really great content keep it up
Thank you! Will do!
nice
fantastic
Thank you!
Very informative
Glad you liked it!
i love this video and this might be unrelated but can someone pls explain to me what OSMOTIC PRESSURE AND OSMOTIC POTENTIAL are
Thank you very much
You are very welcome!
so active transport is from low potential to high potential of something and specialised cells like the muscles need a lot of mitochondria because they retract also active transport needs a lot of power that's why when active transport happens its somewhere with a high concentration of mitochondria (active transport goes against the concentration gradient which is high to low but active transport is from low to high)
Thanks!
No problem!
Cool.
Thank you sir
You're welcome!
gut video, danke !
No worries!
What are secondary active transporters?
Such a good video.
Glad you think so!
Yeah it's true,
It was understandable video........👍🏿👍🏿
so do protein carriers also carry sucrose? pls reply ahaha i'm desp
Thanks a lot
Happy to help
THANK YOU
Cool :)
Bro why these channels dont have like 1 m and 2 and 4 m..why? Why other silly channels have +10 m
Whatever keep going bro watchin and supporting u from iraq ♥️🇮🇶
Thank you! Appreciate it 💜
Yo sir u explain me better than my teacher 🙂🙂🙂🙂🙂
Glad to hear that!
It helped a lot
So glad!
Good video
Thanks
