Fermentation

What happens when you can't do aerobic cellular respiration because oxygen isn't available? Explore fermentation with The Amoeba Sisters! This video focuses on alcoholic fermentation and lactic acid fermentation, and it also mentions how this pathway is different from anaerobic cellular respiration.

This is a quick reupload---sorry about that! We had an earlier version posted just an hour ago, but we noticed a place in the video that had the word NADH instead of NAD+. A typo that would really bother us if it caused any confusion! Fixed now :)

six years later and y’all are still the reason I’m passing bio!! thank the Lord for the amoeba sisters!!

[karo]

I'm homeschooled and I basically use YouTube to learn. I am so behind on biology and you guys make it so easy! I am taking my mid-term test in 1 hour and 20 minutes. Please pray for me. Also thank you, guys, so much, keep up the amazing work.

[rohumhossain]

Even if my exams are not related to your videos, I still watch them solely because how enjoyable they are and how engaging all the materials are. KEEP UP THE AMAZING WORK! :)

[NICKZEMPIRE]

watching this literally 1 min before an online exam during quarantine 2020, see yall in the future l

[laurenpoole]

I love you guys 😭 I was so overwhelmed by this and didn’t understand at all when reading it in my professors power point presentation, but now it makes sense. I love how you break everything down using your cute and relatable characters, making the information seem less daunting. Anything you say that makes a question pop into my head, you answer it almost immediately afterwards. These things make you ladies amazing teachers!

[adriennejanzen]

When I read my micro textbook, my inner voice sounds like you because your cadence and tone make learning easier! So, thanks!

I'm literally reading this biology book of mine and its looking like a weird language but once i watch your videos everything becomes clear and i actually understand. The visuals are the best for me!

you guys are the best. You teach better than my biology teacher. I wish you guys had a school. I appreciate the time and effort you guys put into these videos. They help me so much when I am trying to study or I cant figure out a concept. Thanks for all your work :)

[tatoandmaylo]

Thank you so much for taking your time and making all of these videos! I am a visual learner and it makes everything so easier to learn! You guys rock!

[myfdpoo]

i love how the illustrations are easy to understand and it makes me attentive to the discussion :< i'm currently studying this because we have no face-to-face classes due to quarantine so i'm having a hard time understanding the lessons. thank you for this :>

[khadija]

Im studying for my MCAT & I literally lovee watching your videos because you make them so enjoyable. Thank you!

[rhettmelton]

It's 12:30AM and I wanted to learn about fermentation for the sake of understanding kombucha-making. You just taught me the legitimate process on a cellular/molecular level in 30minutes of watching/re-watching. Incredible.

I now understand aerobic vs anaerobic cellular respiration, the basic role of glycolysis in each, and how in anaerobic cellular respiration the fermentation process (which is tacked onto glycolysis to regenerate the process) is different based on whether it's alcoholic fermentation or lactic acid fermentation.

I feel like a genius. Thank you for an incredible presentation!

[fatahiyakashif]

I was literally studying rn this for an exam!!

[melinagonzalez]

This video is unbelievably useful. After reading endless books on the topic that would only make me feel more confused, in 8 minutes you provided the whole fundamental basis to understand these processes. THANK YOU

[eucalyptus]

Amoeba Sisters, thank y'all so much for your videos! The way in which you present confusing concepts makes it easy to understand and memorable. It also adds a touch of personality, which is nonexistent in the current American school system. Again, thank you so very much!

[dontdisturb]

man I wish there was "Amoeba sister" channel for other science subjects too (Physics and Chemistry ..?) cause this channel is literally THE BEST
