Cellular Respiration: What Food is For
Вставка
- Опубліковано 7 сер 2024
- We eat. But how is that food used by our cells for work? Well, it's quite an involved process, involving glycolysis, the Citric Acid Cycle and the Electron Transport Chain. This video provides some background and an overview of all of these processes. It can be a scary topic, but take a deep breath and find out where that oxygen goes!

Cellular Respiration: What Food is For
General equation for cellular respiration:C6H12O6 + 6O2 --- 6CO2 + 6H2O
Show me the MONEY
Show me the GLUCOSE
Where We Spend Our Glucose:
70%: basal life processes
20%: physical activity
10%: digestion of food (postprandial thermogenesis)
Financial Analogy
Conversion Efficiency
Energy Conversions Produce HEAT
Antoine Lavoisier
Named oxygen (1778) and hydrogen (1783) and predicted silicon
Helped construct the metric system
Made the first extensive list of elements
Reformed chemical nomenclature
Discovered that mass remains constant even though the states of matter may change

I used this in high school during AP bio & got the highest score on my cell resp test out of the whole class. Now I'm using it to help me study for the mcat. amazing video!
you literally save my life every time im preparing for a test. you're amazing
+Breanna McLaughlin WOW - that makes this penguin feel good!!! Thank you.
These videos are a REVOLUTION in learning science. The audio + visual aids make one 15 minute video more effective than hours of reading a textbook!!! Many thanks!!
a professional and fabulous enunciation... I mean while the other youtubers sound like a nine-years old rendering uncertainty in their talking, yours is just epic... and educated
Wow - thanks so much!!!
I knew I would subscribe to this channel right after the introduction. I mean Bio is painful so why not make it un-complicated. My prof said, "for the next class, I will not conduct a regular lecture, so watch this video". Okkkkaaayyy was my reaction, but now I got she was humble enough to realize, "well I cannot do better than this" and my prof is amaaaaaaazing, so lady you are like super amaaaaaaazing. OMG you made this in 2013, where was I????
Wow - thank you so much for the kind words! So glad it was helpful.
I found the first 6'ish minutes of this excellent for my year 8's. Great video for helping them understand cellular respiration.
The rest I'll save for my seniors.
I'm reviewing my basic college chemistry , this is best chemistry internet site I've found , thank you . Greatest of luck in life to you .
Thank you so much! I'm so glad it was helpful.
Love your voice and your teaching.
I'm really appreciating your specific delivery to summary method. I truly want to understand it this well.
thank you. I'll be watching these video next semester too because I found these too late. but you explained 3 hours of class in. 15 min.
I've never studied biology or chemistry before, but these videos are so fun to watch! Thanks for taking the time to make these :)
So helpful! Your enthusiasm is very encouraging :) I can hear you smiling as you're talking!
thank you so much, you made this topic very simple to understand yet providing in depth details. I have subscribed and excited to check out your other videos. You're awesome xx
+Rinas Rashid I am so glad you found it helpful - and so glad you subscribed!!! Much more on the way so stay tuned!
this is the coolest cellular respiration on the planet
+Sara Fahad Thank you!! So glad you found it helpful!
Wow, what crazy super smart scientists figured this stuff out!
Thank you, this was so well explained and easy to understand.
Thanks for this well put together video!
THANK YOU for making this so easy to understand and ENJOYABLE to watch!
So glad you found it helpful!
Really exciting! Great work!! Thank you, greetings from France!!
+TUSENSLEPATAY Merci beaucoup!
excellent video, actually boosted my confidence in learning about cellular respiration. I felt completely overwhelmed till I had viewed this video. Much appreciated!!!!
This is great!! Congrats for the excellent work. It's extremely useful for students and future teachers as myself! :) Thanks from Spain
Thank you so much for making biology so easy penguin!!! Ur amazing!!!
The Citric Acid Cycle is also known as the Krebs Cycle.
Excellent video -- thank you.
+Fred Pauser You are welcome! Thanks for watching!
EXCELLENT VIDEO AND TEACHING THANK YOU SO MUCH.
The energy is stored in bonds between the atoms of molecules; breaking those bonds releases the energy, just as building the bonds requires energy. We break bonds from food molecules and store the energy in ATP molecules, which cells use to do work. Hope that helps!
I'm learning so much from your videos! Thank you!
this video is so good and well done. i am a student from Italy willing to study Medicine in English, and i found this video (as well as many other videos) very useful! thanks from Italy
Your explanation are awesome!!!!i love it.im not really good at english,cause im not the native...but your explanation use easy and simple english,and you rarely use "scientific term".keep up making video.this is really helping.
its amazing explication ...thank you
i love your "back in the day" ref to the creation of life
I like all your lectures, wonder whether can get your ppt file, so that we use some of them in my own lecture, thank you for your great work! Keep up!
Excelente! Muy claro y preciso el video
I do recall playing Hot Potato as a child in the 1970's ONCE at a birthday party, but I had no idea it was a formal game by Remco
Wonderful explanation
You are amazing! I love how you put (and connect) everything together! Can you replace my Biology teacher?
Thank you soooo much penguin Prof.!!!!!!!
Wonderful! Thank you so much. I think this will help my students.
+Anita Lemon I'm so glad - thank you for sharing it!!!
I am sorry - I cannot provide ppt files due to tmy agreement with publishers for using some of their images (I am allowed to use them in videos but not to publish them in a downloadable format). Sorry I cannot accommodate your request.
Excellent!..Muchas gracias
you're brilliant
IT ACTUALLY MAKES SENSE NOW thank you
Unbelievably useful!. Thanks from your student across the sea.
a beautifully constructed video. I was a bit thrown off by the sexual innuendos at 14:30 lol nice touch
Stunning, awesome. I love your presentation skills!
YOURE AMAZING, THANKSS
Amazing!
im going to use this video to help me study for my final. Thanks so much
GOOD LUCK with finals!
great Video i have a question about the Mitochondria i try and study its connection to Cancer and you said the food is like currency giving it to the bank like Mitochondria changing food into ATP "Mainly" who else dose that convertion ?
Some ATP is made by glycolysis as well (in the cytoplasm).
please add these topics like buffers,trace elements in biological system,vitamins,
This dude got a plain burger ok don’t blame all of us for eating a normal burger dyed red. This video made me lmao though
Sees the $5 note
Me as a kiwi: YES
Love NZ and ALL of your penguins!!!
But profe, Where does oxidation come into this process? And, oxygen good or bad?
THANK YOU!
Aaaaamazing!
Ma'am superb
Could you please explain where energy is stored in food?
what are waste products of cell reparation and what system of the body is directly tied to the handling of the cellular waste?
Its been 3 years, but the waste products are CO2 and H2O. The respiratory and excretory systems handle the waste
Ciao e grazie per la scrittura! Sto studiando l'italiano! (Il mio marito e' Italiano - di Milano). :)

interesting video
You're awesome Penguin Prof!
How come the protons can only fit through that one place? The smaller Hydrogen protons should be able to go through anywhere not just the ATP Synthase? What is the inner membrane made of so that Hydrogen protons can't just go through? Ok, too many questions.
I know you asked this ages ago, but in case you're still interested:
You're correct that the H+ ions (protons) are tiny, but they're also charged. Cell membranes have a sandwitch-like structure with charged surfaces and a non-polar (non-charged) center. As a general rule, like disolves like. The protons can't diffuse directly through the membrane because they are charged and the center of the membrane is not.
SomeoneBeginingWithI Thanks for that, so basically it is the 2 opposite charges that stop the Hydrogen protons going through. Cheers.
Excellent work thank you. Please do a video about mitochondrial uncoupling protein :)
The best😘😘💯💯💯
Woo hoo!!! Thanks! Glad it was helpful.
ye same your the best
Thanks so much!
"[Food!] What is it good for?"
Is what makes ATP, but you only get 40%
I have a much better handle on this now thank you!!!!!!
Thx M8
Greatttttt👏👏👏👏👏
Thank you! Cheers!
thank you!!! the text book made no sense thx god i found this video
Thanks for infomation, you are god to explane, But i need it in Swedish :)
This is really hard to understand

You tried!
Was made to watch this , but it was ok :/
Now I'm all sad and depressed about the destructive patterns of human behavior -- idiots murdering geniuses throughout history, and all that. I can't concentrate on biology any longer...
my teacher made me do this for a homework assignment and i no longer like you
That's OK. There's a lot of other stuff to like in the world.
