The mitochondrion is the site of cellular respiration, a process which takes stored energy (glucose) and turns it into useable cell-energy (adenosine triphosphate).
Can we all take a moment to appreciate the effort and mostly the humor these girls have put in the video? Thank you so much amoeba sisters you are amazing at explaining so easily and understandably difficult biology mechanisms !! I would love to see a video about Krebb's cycle!!♥
It’s amazing how much more I absorb watching these videos. Speaking for myself personally, i’m dyslexic and also have ADHD and I’ve tried various methods of learning. These animations has been by far better than any outline/PowerPoint I’ve ever been given. Watching this helps with getting the information to stick! Thank you so much for these videos keep them coming!
Ah, you guys got me one unit late! Nonetheless, your videos helped me get a 97% on my midterms, thank you so much! You do not realize the significance of your videos, and the assistance they provide to those who sincerely require it!
Absolutely fantastic. I'm showing this to my A&P I nursing and allied health students now, and it's helping a great deal with distance learning! Nice work!
The machines working inside our cells are so amazing. We are so incredibly well engineered :) I'm just an old guy who enjoys learning. Keep doing what you do :)
As a teacher I always use your videos for my lessons, I’m considering signing up to be a patron too because I really love your work!! I would love to see a video on Photosynthesis (light dependant/ independent reactions) and respiration (glycolysis, Krebb Cycle etc..) as these are topics students always struggle on.. THANK YOU @AmoebaSisters ❤️❤️
Hello teacher, I have a question Why use the carrier protein instead of the channel protein? The potassium can exit out of the cell through the channel protein right? So why not use the channel protein?
@@blast8012 In my opinion, because channel protein cant take the potassium back to the outside of the cell (extracellular cell). Channel protein only provide molecules from outside to the inside cell (intacellular cell). Carrier protein provide the molecules to in and out of the cell
I don't care about what anyone says about science, I can clearly see some Jojo references right here 0:27 *Pillar men moment* 2:32 *Sunset Overdrive* 4:13 *That's a WRYYYYY I think*
Watched these videos in highschool and they have me coming back in college! So unbelievably helpful in a pinch for exams and it's a major plus that the art is adorable and simple.
thank you so much for all of your videos! I opted out of Bio and chemistry in my last two years of school, but then decided to study bioinformatics and you're SAVING me. My teachers always expect everyone to have the basics down already, but I'm literally dependant on videos like these that make stuff so easy to learn, so THANK YOU
These videos are so helpful! I don't know why, but someone could give me the exact same information, but your videos just make it so much easier. Please never stop!
Love it. This topic is the reason why if to from my AMP class. But this video seems very comprehensive. I know I probably will have to re- watch it for like 20 times untill I get it.
a 7-minute video it turns into a 10-minute ordeal because I have to pause and rewind because I start giggling too much at the cute cartoons and I lose track :D Thank you for these videos! I'm currently in nursing school and having to refresh some basic concepts and these videos are so helpful! Why can't everything be explained with cute cartoons?!?!
I would 100% be lying if I said I wasn't grateful that the amoeba sisters exist because dear God isn't hard to understand this stuff outside of these videos
I love this simple way of explanation I also love the cute graphics, they make me smile I wish I could get my education in university as simple as that I wonder why your platform is not created yetPlease, I want full explanations of medicine You're videos made me love to study You're the best Thank you amoeba sisters💕💕
never ever would i have thought that i would be watching these super cute videos for my university bio lab class. i absolutely love your videos!! too cute :,)
The teacher doesn't wanna teach, she pulls out these videos. You got an exam you say? Pull out these videos. They totally nailed it with the visual appeal and visual learning.
I love your channel so much. Biology is so bad that it makes me want to cry, but your easily digestible yet in-depth (seriously, how do you guys do it?) makes it better. :D
your videos are incredible, i am so grateful that you have such a backlog to watch and are still uploading new content!! :) my prof posted links to these for us and they are so helpful. thanks!
I love watching videos that include images as it's somehow easier for me to recall info that I have seen that uses colour, than just plain black and white. New to this channel but like it already.
You have no idea how useful this is to me! Thank youu, your videos help me to understand the concepts that takes hours if I were studying em using the text books. God bless you both. Love from sri lanka❤🇱🇰
Your videos are really helpful. I‘m from Germany and my biology (bilingual subject) teacher showed us this years ago. I still use your videos to learn and i graduate this month ☺️
Love this channel ❤ I have my test today and I'm so worry😕 about it but now your videos will help me in revision thank u so much😍 Keep it up it help a lot great work! Thank u ❤🤗
The amoeba sisters are AMAZING!!!!!! I cant believe that Im just discovering your channel. Everything I nee to know is explained and some how it all sticks in my brain. God bless you ladies! Please don't stop making videos.
Our books are confusing as hell and don't offer much explanation, as such our teacher loves showing us your videos so we grasp the content better! After watching them I always let out that "ohhh" as you do when you finally understand something. Keep up the amazing work, you're helping a great deal of people!
Im at a school were the core subject is biotechnology and I loveeee your videos, they make my studying sessions so much easier. The best part of it all is the humor. Please keep doing what you’re doing
1:20 The sodium potassium pump requires an input of energy from Adenosine Triphosphate (ATP). One major function is to help maintain a resting membrane potential between Na+ and K+, two ions with positive charges that have trouble traveling directly through the plasma membrane. As a result, they require a protein to travel through (either a channel or a pump), in this case, the sodium potassium pump. 1:54 Resting membrane potential involves the cell's electric potential. EP is the difference between the electrical voltage inside and outside of the cell. Cells have their own resting potential depending on the type of cell. Generally, most cells are more negative inside the cell than outside. 2:15 For many cell types, when this resting potential is changed by some type of stimulus, there's a response. Muscle and neuron cells are excitable cells and many of their functions depend on a change to their electric potential - explore action potential for more details. For a cell at rest or if it needs to return to its resting potential, the Na+ K+ pump is very critical. 2:51 The Na+ K+ pump is initially open on the intracellular side of the cell, it has binding room for THREE Na+ ions. When these three sodium ions bind, the protein is PHOSPHORYLATED (ATP transfers one of its three phosphate molecules to the protein and changes the protein's configuration/shape. The shape change causes the pump to open to the outside (extracellular side) where the three Na+ ions leave and TWO K+ ions bind. The protein reverts back to its original shape within the intracellular side of the cell. The two K+ ions are released within the cell. Now there's room for three sodium ions and the cycle repeats. *THIS PROCESS MOVES SODIUM AND POTASSIUM AGAINST THEIR CONCENTRATION GRADIENTS*. With this active transport, the ions are moving from LOW concentration to HIGH concentration since there's already more sodium OUTSIDE of the cell and more potassium INSIDE of the cell. 4:45 Voltage difference in the resting potential is caused by more potassium ions inside the cell and more sodium ions outside of the cell resulting in an electrochemical gradient. This means there's not only a difference in charge but also in the actual ion types. 5:27 Many cells have far more potassium leakage channels than sodium leakage channels. This makes the cell membrane more permeable to potassium at rest. Positive potassium ions that travel OUT of the cell contribute to a more negative charge INSIDE the cell. 6:02 There are other ions that can contribute to the resting potential as well. 6:17 There are other proteins that rely on the electrochemical gradient to move critical molecules. Proteins that move in glucose are an example.
I’ve had freakish muscle cramps since I was a teen and I found L. M. N. T. Last year! It has been a game changer!! Unfortunately I hv to take 6-7 packets throughout the day and each packet is 1000 mg of sodium. One would think that my bloodwork would show that I have abnormally high sodium, but I don’t?! I’m trying to get to the root cause of this and I hv an appointment to see a nephrologist this week in hopes of answers?
To be honest I would have failed science by now without this...... I know that you often say "To the Google!" but I never need it. You guys are awesome! Also, once your'e done making science videos, you guys should start making vids about how to draw like Petunia. ;P Even though Im already forever in ur debt....
Question (I may have missed something) if those pumps are always pumping 3 ions of sodium out of the cells and two K+ in. And sodium has a hard time getting through channels to get back inside the cells. At some point wouldn't that mean there would cease to have any sodium in the cells? 3 Na+ out and 2 K+ in. I know 90% of the intracellular is K+ but how is it that the cell has so much Na+ to pump out?
Thank you for good video! I'm Korean high school student and writing a report about biology. I couldn't find adequate materials in Korean for my report, but it's ok with your video.
I just started studying health science, your videos are amazing! great at making the concepts understandable and the illustrations and captions are hilarious. :)
