Active Transport Explained

- This animation explains active transport across membranes and why it is needed!
Transcript:
Naturally, molecules and ions move from areas of high concentration to low concentration (down their concentration gradient). But what if you need them to move the other way, from low to high concentration (against their concentration gradient)?
This requires energy and is called active transport. In active transport, ATP energy and transport proteins are used to pump particles against their concentration gradient, from low to high. Because this is going against the flow, it is like swimming upstream or pumping water uphill, and therefore requires energy to be used. It is easy to remember that active transport requires energy because doing active activities always uses energy.
This is important anytime you need to concentrate a substance on one side of the membrane. In our sugar example, for instance, you might need to pull more sugar into the cell, even if the environment has a lower concentration. In this situation, your cell would use active transport. Remember, active transport uses ATP energy and transport proteins to pump particles from low to high!

You are by one of the best teachers I have seen online by far. Your videos are consise and clear. And your animation makes everything click for me. Thank you so much!
Thanks!
Straight to the point, thank you!
You're welcome! I'm glad you enjoyed it!
Thank you for the great explanation!
Thanks, I'm glad you enjoyed it!
Really good as a teaching aid - thank you!
Thanks! I'm glad you enjoyed it!
bioman on top >>>>
Very well done, Bioman!
Thanks Alison!
Thank you for uploading! 🙂
You're welcome!
Your videos totally rock and help me immensely, I haven't watched your newer videos so I'm not sure if you've taken this into account but the bg music is very distracting and I think lowering it/not adding music would make your videos even more enjoyable to watch. Thank you very much!
Thanks, I'm glad you have enjoyed the videos. Some other people also have commented on the background music being distracting so I'm taking that feedback into account moving forward. Thanks!
That was simple and précised 👍
Thanks, I'm glad you enjoyed it!
Thank you so much!
You're welcome, I'm glad you enjoyed it!
wow. this helped me so much i have a test tommorow!
Great to hear! Good luck on your test!
Same
I have a test today haha
Same here
This is the easiest video to understand ever! love this channel, deserves way more fame, now I won't fail my exam!! :D
Thanks, I'm glad you found it easy to understand! I hope your exam goes well!
Hi! I actually haven't gotten m exam since then so at least I can keep watching!! Thanks for respond! :)@@BioManBiology
Perfect ❤️
keep going ☺️
Support From Egypt
Thanks for your support!
Super helpful.
I'm happy to hear that! Thanks!
Thanks for complete my concept
You're welcome!
Bravo professor,Ilove your work
Thanks, I'm happy to hear that!
I’m struggling with this, i have to re-sit a test on monday and i just don’t get anything, its so difficult, any help is appreciated
Can you make a video about primary and secondary active transport
Your aid sir is simple and excellent
Thanks for the kind feedback! Perhaps someday I will get around to making an animation on that, but it might be a while since I have many other projects. Thanks for the suggestion!
Thanks, i have covid so i cant go to school, so im happy to have this video
I hope you get better soon! Glad the video is helpful to you! Thanks!
Thanks sir👍
You're welcome! I'm glad you enjoyed it!
I did a presentation on this in 1996 for high school Biology. I said the same thing. I used Encyclopaedias and dialup internet when I could. I even had a GP (doctor) help me with information and for references. I got a C+. I showed the GP that helped me and he made a call to my school and got my grade changed to an A. The teacher didn't like my delivery but all the information was there.. it's not a performing arts class.
I'm glad you got the A after all. I went to high school in the mid to late 90s too...it was a different world then... information was much harder to access. I hope you enjoyed the video!
Can you do about passive?
Yes, I have done several on passive transport. Check out the videos on diffusion and facilitated diffusion (both are examples of passive transport (transport that doesn't use cell energy).
@@BioManBiology ahhh Ty!
I am watching this video for homework and one of the questions is “What molecule does this become after ATP is used to transport sugar into the cell?” Does someone know the answer? I really have no idea, great video by the way!
Hi, it's a little difficult to know which molecule is being referred to by the question, but I'm guessing it is referring to ATP. When ATP breaks down and releases energy it loses a phosphate and becomes ADP. Note: ATP (Adenosine TRIphosphate) has 3 phosphates, but ADP (Adenosine DIphosphate) only has 2 phosphates. Note: all caps are meant to emphasize the prefixes "tri" which means 3 and "di" which means 2. I hope that helps!
@@BioManBiologyThank you! It really does!
For the quiz
Good luck on your quiz!

hi
This was a well made video but don't make listen to that trash music.
I'm glad you enjoyed the video. I'll keep your suggestion in mind for future videos. Thanks!
