How do cells get their energy? (Electron Transport Chain): Crash Course Biology #27
Вставка
- Опубліковано 16 тра 2024
- You know ‘em, you love ‘em. They’re the powerhouse of the cell: mitochondria. They produce the ATP molecules that we use to do everything from talk to our friends to run a marathon. In this episode of Crash Course Biology, we’re taking a deep dive into cellular respiration, the process that produces the ATP inside of our mitochondria.
Chapters:
Getting Energy 00:00
Mitochondria & ATP 1:22
Cellular Respiration 2:29
Glycolysis 4:18
The Citric Acid Cycle 6:40
The Electron Transport Chain 8:17
Review & Credits 11:05

How classy to credit your student coming up with the currency exchange model. Sammy is a fantastic educator. Love this channel!
Ah yes, I remember having to stand up in front of my biochemistry professor, Dr Robert boyd, and explain in detail the citric acid cycle. He was the chemistry department chair, and he was a brilliant researcher. I learned a lot from him.
my biochem professor was of Indian/pakistani descent... he knew his stuff...📚
AMAZING the world we live in today with the opportunity to learn science so well presented on a platform known for entertainment. What a time to be alive! Thank you, Doctor Sammy.
I had a great biology teacher, she was only marginally more unsuccesful in teaching me this one. This is a serious step up from previous episodes.
It's Regents today and we start it in under an hour, thanks for this useful video!
As a Biochemistry student I really enjoy watching videos like this.
always amazed by the cycli of energy in our body
Thanks for this video. Great information.
I was studying this topic I swear 😂.
Thanks , this video helped to make some additions to my note.
(New subscriber here. Love your videos)
Oh my god! Me too. 2 days ago I was looking for a video on ETC and didn't find a good one . And today I get this in my home page!
Im taking an Environmental Toxicology course right now. It gets EXTREMELY nuanced.
That "currency exchange" seems like it starts with wood and cotton and manufactures the whole bill rather than just exchange one currency for another. I love the metaphors and allegories you came up with.
I have been trying to find a video on this earlier today. Exam's in less than 2 weeks, just in time. Thank you!
Thanks for all your great advice. I really enjoy watching your videos, they provide a lot of knowledge and are very helpful on a daily basis in choosing food when shopping, etc. Thank you ❤✨
You reviewed the material we are rereviweing and expanding on in my Environmental Toxicology course!
My energy cell aka mitochondria didn’t form properly. Therefore it’s like running on low battery for me 24/7. Weeks really like your videos. As I’m homeschooling we find these so fascinating and very informative
Very well done, I think!
you are the best ❤
Keep posting, your follower from Iraq ❤
oh man this video comes in clutch to understand that recent "Nah, I'd win" mitochondria meme
The electron transport chain and oxidative phosphorylation was the topic of my masters work. I met Peter Mitchell. 😊
I wonder how long it took for science to find out all of this and how the hell they did it
Waiting for Crashcourse microbiology
i'm taking physiology and microbiology right now, that would be great, specifically case studies.
Ugh u uploaded this to late I just had my final today but great info as always 😢
I'm with you. 100lb of ATP a day sounds crazy.
The citric acid cycle is essential
the mitocondria is the powerhouse of the cell
ATP ADP I remember studying about it back in 2015
So, ATP is not very energy dense, if the energy of a single glucose molecule can make 30 ATP molecules. 🤔
🔬 10 million ATP particles are made every second...
🔹 if you take the reciprocal...that means ...
🔬 1 molecule is made every 100 nano seconds...
⚡ that's lightning fast ⚡
I need that microscope! 😭
😁
12:35 But 10M ATP molecules... ok, but
1) how many ATP molecules does the cell need per second?
2) Or does it vary depending on the type of cell?
3) Do some cells produce (and use) more ATP than others?
4) Does the number of ATP produced and used vary throughout the day?
5) Does the number of ATP produced and used vary during different activities (eg: thinking vs doing sports vs dreaming)?
This gave me more questions ...
Quantum physics
Love the fancy outfit Sammy!
I'm here for something else.... I just got to know that this is also a channel of John green .. sir, I just finished fault in our stars and I hope you have a good night after crushing my dreams ...
WHY DID THIS RELEASE RIGHT AFTER MY EXAMS WERE OVER 😭😭😭
Microbiology
A❤
🎉🎉🎉🎉🎉
How do we use 100 pounds of ATP daily if we don't consume 100 pounds of food? And if we do, it would be used with total efficiency and we wouldn't need to use the bathroom
This is a great way to microwave scientific information.
I saw a jujutsu kaisen edit of this
How much is 100 pound?
Please at least write in kg/g in the edge of video because everybody is not familiar with fps system
WHAT? You're telling me my body is preventing me from exploding naturally? I am disappointed.
Also, if you're a hundred pounds you are way smaller than I thought, that's half my weight.
I'm still stuck on the fact that Sami weighs 100 lbs.
I need turkish language
first
What is this CLICHE COUNTER thing??😐
Why can I comment
