Sal, I can't tell you how many quizzes and test you've helped my son pass. What you're doing is incredible. Free tutoring services for all! I've donated, but it doesn't nearly compensate you for all you have done. Thanks!
this gentleman's voice is easier to listen and learn from than the others. I wish he did all the physiological videos
So…how does the food industry get lactic acid, does it always involve milk?
I love Sal. Every single topic you discuss is so wonderfully explained. I have learned so much from Khan academy. I seriously watch these videos daily! Fascinating stuff!
This video has great timing I'm taking my bio final today
I’m taking my AP bio final in few mins 😭
This video is unnecessarily complicated. It's ok but not so great!!
finally a video on fermentation liked and subbed
For those who don't understand the video completely, I recommend you guys read about it in a text book then watch the video it will make an absolute sense. Great video, Sal. God bless !
+Ali Saleh For sure, my final is comprehensive and I seem to have forgotten the details...but this was too detailed lol
Ali Saleh are you from balambat
It would be useful in future videos to show how steps obey the electroneutrality principle. I certainly struggle applying this principle to biological processes. Otherwise a very helpful video.
It also happens in our muscles during anaerobic exercises, our cells switch to this metabolism due to lack of oxygen and produce lactic acid, which gives us muscle sore.
why did he end up with two different products at the end
I like your funny words magic man
"Hopefully you get a kick out of this. I know I do" Haha, that was funny. Anyways, great video; it was very helpful.
help me why is sodium hydroxide used to measure lactic acid value
So is fermented food beneficial? I thought the body needs ATP not lactic acid. Where can I get more info on this?
The supposed benefits of fermented foods have nothing to do with their ability to provide energy (ATP) and is to do with the beneficial bacteria contained within the fermented foods.
We need lactic acid where we cant get oxygen directly like in some muscles during extreme physical properties.
love this channel man
c ette vidéo est complete mais complexe a comprendre
But good also
Is lactic acid fermentation an indefinite or temporary process? What ultimately stops lactic acid fermentation?
WOW, AND THANK YOU. I have been looking for this explanation, SwEeT!
Where would we be without you Sol - after struggling in the dark for weeks getting maybe 5% Khan Academy switches the light on, again - Thank You
HELP PLEASE. So, Lactic Acid Fermentation does not use O2. And Pyruvate is used to oxidize NADH to NAD+ and the NAD+ is used to perform Glycolysis again, right? So what happens to Pyruvate? Is it going to be oxidized (reduced?) to Lactic Acid? If so, what is the function of Lactic Acid? And how are we going to use Lactic Acid as energy? I’m sooo confused here.
Well the pyruvate is converted to lactate. We can't use lactic acid as energy. All it does is removes the hydrogen from NADH (during the conversion of pyruvate to lactate) and converts it to NAD to go through glycolysis again. Lactic acid can cause pain in the joints.
When we get oxygen, the lactate is carried by the blood plasm to the liver. 20% of it is oxidized to carbon dioxide and water; the rest is converted to glycogen.
@@rinu8835 how can we end up with lactic acid in tbe body when our cells only produce lactate ?
@@nsn27 He said the lactate is carried not lactic acid. But if he meant to type lactic acid, then you should probably research more in-depth by yourself to know the answer.
He said that a hydrogen proton, electron and another electron is removed, then both electrons attached in the pyruvate, and the oxygen grabbed a hydrogen proton from a passing water molecule, what happened to the original proton?
So where does the energy come from? This was never explained.
The sun
ATP is energy. you get it from glucose
Do you wanna know?
I wanna know about lactic acidosis vs DKA plz
in a nut shell is lactic acid good or bad for body
1:40 THAT'S WHY I'M WATCHING THIS VIDEO!!
Will it bubble when fermenting
Wow! Thank you.
Is this the same as anaerobic respiration??
can you translate it in italian?
+Naomi Oliveri You can turn on the CC and put the words he is saying in Google Translate.
or you could learn english
@@centralhicksiv4468 English is hard if your not a native, not to mention it breaks its own rules. It would be easier to google translate it.
My teacher told me to watch this and I understand nothing, not a single word. Ugh

you talk way too much just get to the point please.
Christina Charles some people here would like a detailed explanation, if you want a fast explanation maybe read the textbook for a change or find another video
