You and Khan Academy have helped me MULTIPLE times...thank you SO very much!!!! I wish professors taught it like you did, but I'm so glad you offer this assistance to us struggling students. YOU ROCK!!
As a visual learner it's tough to follow at times in class with no images or means of picturing whats going on. Your videos make learning understandable and easy. Thank you!
One of the most refreshing teaching voice i've heard
0:50 wohhh language!!!!!!
OMG, I am so glad I found this Khan Academy. Your videos are AWESOME!! I just started BIO and Physics. The physics class is kicking my butt. I am taking it online and being that I am a kinetic learner, just reading everything and trying to comprehend is a struggle. I hope to find some videos as AWESOME as this one to help me through that course.. Being that I am so lost already in the physics class, I have been thinking about dropping it, but if I can find videos like this to help me through, I might just actually be able to tackle it in the online setting... THANKS TO YOU!! I have spent HOURS watching other videos and 30 seconds in I get frustrated because the instructor is stumbling, stuttering, coughing excessively, with an accent so thick I can't understand, or just so much other background noise that I just get frustrated and confused... Can't wait to find some Physics videos to TEACH me.... THANK YOU!!
omg. u r the best! the understanding this stuff is made tangible....thanks!
Thanks for the help... your drawing is amazing btw
jdjdjdidudfudoeimDMGOYUDBAAKUDJJ😍
Thank you for saving my life!!!!!! I understand a lot of bio now because of you.
I am amazed by how understandable your videos are. Thank you.
You’re a life saviour
love the manns khan academy, Bless you bruh
For simple explanations and easy understanding I would recommend Khan Academy to everyone searching for solutions to biology questions
This helped me alot! Thank you! You're awesome :)
not all heroes wear capes, thank you
Thank you Sooo much sir ,, thank you . . . 🙏🙏
damn. life saver. thanks mate
i was clueless before
Videos are awesome keep it up!
Dude lol! Your an artist!
thank you so much Now I understand 😌😌
thanks that was wonderful
Incredible drawing!
the art on the latest batch of cell videos is awesome.
JZoidberg. Nice
U r grt
Thank you 😊 sir
thank you bestie
When Khan says the carrier protein flips, exams prefer you to say it undergoes conformational change, as in the shape changes. It technically does not “flip”.
Doesn't the carrier protein require energy to change it's configuration?
What is the difference between permeases , carriers and pump?
First Comment.
water moiecules are able to pass through simple diffusion as well
yes this goo

3:18 lmao we all knew what was on his mind.
Who downvotes a khan video?
Wonder when he's going to upgrade to a better mic and 4k or 1080p
perhaps when it becomes a more serious issue that you cant see drawings of circles and lines in high detail
@@hungrymonk3645 I mean its a pretty serious issue since it physically strains my eyes to the point where i can't watch.
@@AccuphaseMan i think you have a problem with your eyes brother, or perhaps your screen is too bright/environment is too dark
i dont think changing a video from 720p to 1080p will really make much of a difference if you are already physically straining your eyes
Does he not have problems with his tools every video LOL?
Thought he said Aqua porn
Had to explain it to someone one lol
lol
