Don't let your teacher affect your love of science. You can be a scientist outside of the classroom too. Be your own teacher. Keep your love of learning and you will do just fine.
Whoa, you honestly made everything clear without me having to look over my notes and textbook all the time and to memorize the whole steps of glycolysis which confuses me sometimes. You are very neat. You showed helpful visuals, flow charts, good facts, and clear explanations. Seriously, THANK YOU SO MUCH sir. I'll be having a test sooner this week and I feel pretty confident now!
Thank you VERY MUCH Craig for these videos. I see you put in quite an effort and time to make these videos to it completion there. Your tutoring is very clear, to the point, and learning re-enforcing. I understand the whole process or should I say processes now. This is much better than sitting through lectures for hours. Thank you again!
While this seems like a detailed look at glycolysis, I have actually left out many intermediate steps in this very complex biochemical pathway. So some things seems to appear from nowhere like these two extra phosphate groups. The conversion of PGAL into BPGA actually occurs in two steps with the enzyme "triose phosphate dehydrogenase" First it transfers the Hydrogen to NAD+ then it add the Phosphate groups to the oxidize PGAL- These phosphates are FROM THE CYTOSOL (available raw materials)
Thank you very much I am french kid in high school taking both Bio courses at the same time and im doing the advanded one online and Im pretty sure I understood more in youre 9 min video then in his 3 classes on Glycolysis. Thanks Again :)
It's 4am and im currently watching this to pass my anatomy exam tomorrow and I about lost my shit when this vid started giving study tips lmaoooooooooo
i just want to say that your work is appreciated it really helped me study and understand cellular respiration, your are very knowledgeable guy. May Allah guide you in the right path!
I get glycolysis now , thank you. At first I was confused with all the big words and numbers and I thought it was hard , but now its kind of easy to me.
Thanks you so much! Your video is amazing. I am a Paramedic Student and you really helped me. I'm going to be so much better at my job now that I have this knowledge as a foundation. Dude you are such a good teacher!
Yes, this is the best video that explained about Glycolysis. But biology is most difficult to me. I need a lot of time to research it. I will never overcome this unit, because no time for this..........
38 ATP is the number of ATP formed during the process of cellular respiration. 2 are formed during glycolysis and the other 36 are formed in the kreb's/citric acid cycle.
Confused. During the first step, 2 ATP molecules are used to split the Glucose molecule in half, thus leaving 2 ADP molecules. During the BPGA step, those 2 ADP molecules become 2 ATP molecules via substrate level phosphorlyation; in which BPGA becomes PGA. HOWEVER, if those 2 ADP molecules have already been used.. how does another 2 ADP's get used just before the pyruvate step?
great video, thank you but i have one question... how did u get BPGAL out ot PGAL in 5:03? where does the second phosphate come from? i understand that aldehyde is oxidized to acid while reducing NAD to NADH but what about the phosphate?
Hey there, I think the term you're looking for is cytosol. The cytosol is the liquid part comprised mostly of water in which all the organelles of the cell reside, while cytoplasm is a collective term for the cytosol PLUS the organelles in it. Technically, since it's not taking place in any organelle (like Mitochondria), Glycolysis DOES take place in the cytosol. Hope this helped!
shared this with my bio class....great video for overall understanding...Thanks for taking the time to create it.....several of us focus too much on the minutia of the process and less on the overall understanding.

[serious] when the phosphorylated PGAL molecules reduce NAD+, where do those two additional phosphates come from to make the BPGAL(?) sorry can't remember what the molecule is called.
Hey man, just wanna check with you. I noticed that phosphoglyceraldehyde(PGAL) and phosphoglycerate (PGA) both have the same structure. Are they both different or they are actually the same thing?
When the NAD+ gets reduced into NADH I saw that an extra two (P) were added to the other end of the PGAL, does this mean when NAD+ gets reduced to NADH an extra two phosphates are added?
Chemiosmosis drives oxidative phosphorylation. Chemiosmosis describes the build up and flow of the ions across a membrane. It is okay to interchange the terms but know they are slightly different in what they are saying.

I wouldn't be half surprised if this narrator was the radio disk jockey of a late night smooth jazz radio station..
You're a good teacher. I understood everything. Thank you.
This introduction scared me. I felt like big brother was watching my every move
lolll
- I have been studying this topic for 2 weeks and I'm just now comprehending the process. Thank you!!!!!!!!!!
Excellent! Concise, to the point and convey the necessary information without all the fancy graphics or music. Thank you!

I consider u as my Medical College teacher, a wonderful teacher, who is always available to help me to understand difficult topics
This is the best cellular respiration series I've seen & this is my 4th quarter of biology! THANKS!
Love your vids! You're like the Bob Ross of Biology! Thank you!

Thank you again!
absolutely amazing, the only video that made sense about Glycolysis. Thank you
Excellent teaching style. For all the animations out there, your teaching style makes this process, simple and understandable. Thank you so much : )
FOR REAL!!!! My bio teacher is a QUACK!!! I learned more from this video than I did from 2 classes (3 hours long)
You are actually so good at teaching things. Your methods are wonderful! Thank you so much
Very well paced and that too with accurate information.Great way to flip your classroom!
you are perfect! there are many videos like this but anyone of them is good as this one.
ALL YOUR CELLULAR RESPIRATION VIDEOS HELPED ME DO WELL IN MY TEST!!!! THANKS SO MUCH!!!
All of your videos just BLEW MY MIND! THANK YOU!
His videos played a tremendous role in me passing my biology in my first year in medical school!

Thank you very much, this was the clearest explanation I've found so far.
for the first time I got an A on a biology test because of studying your videos! I seriously cannot thank you enough
you are not the only one that took an A on biology exam, this man is the BEST!!!
I never make comments or like videos on youtube but not this time! thanks, your video helped a lot!!!
Thanks for the opening tip regarding passive and active learning! This is very helpful.
Thank You so much ! You made this complex process so much easier to understand!
You are awesome Craig,I also really learned a lot from you. and you have a nice voice.
coccananona -
this bro has me falling asleep in science class every day
I can't believe that you helped me understand this! THANK YOU! You saved me for my test! :)
Thank you very much I am french kid in high school taking both Bio courses at the same time and im doing the advanded one online and Im pretty sure I understood more in youre 9 min video then in his 3 classes on Glycolysis. Thanks Again :)
wow finally enjoy learning about cellular respiration. Thank you!
It's 4am and im currently watching this to pass my anatomy exam tomorrow and I about lost my shit when this vid started giving study tips lmaoooooooooo
This is extremely helpful, thank you so much!
Excellent teaching style!!!!
Great videos, thank you so much for explaining it so well.
Very very very helpful video!!! I have a very much clear understanding now!!!
Thank you very much. Your videos are incredible and very easy to understand.
Thank you for this helpful video.on 5:42 it is said that NAD+ turns PGAL into BPGA. where does the second extra phosphate group come from?
Better than my school teacher!
Awesome!
Great job. Thanks for sharing!
Is there video footage that demonstrates each of these steps in this process?
Simply loved your suggestions . Thank you so very much.
Thank you so much, was really struggling with this in class but you made it so easy to understand!
i just want to say that your work is appreciated it really helped me study and understand cellular respiration, your are very knowledgeable guy. May Allah guide you in the right path!
Thank you, very informative and interesting, I will keep building on what I have learned for what it's worth.

Dude you are such a good teacher!
You're my fucking hero!!!! College level here and you explain it better than my professor.
very nice vedio....the concepts are clearly explained.....thanx...
OMG! This video is amazing, thank you so much :)
Yes, this is the best video that explained about Glycolysis. But biology is most difficult to me. I need a lot of time to research it. I will never overcome this unit, because no time for this..........
Thank you SO much, that was very helpful !!
i think you just saved my life.
Thanks u sooo much for putting your time posting videos, u are amazing!!Please continue posting more videos.
This was so helpful, thank you so much!! :)
I liked your explanation, thanks!
Thank you so much for making this excellent video, it helped me understand glycolysis easier than it would have been if I looked through websites xD
this is great video and your voice is soothing!
You are truly a life saver sir.
i have a question! why are you so awesome for making and posting these?!?!
Great simple explanation !!!
I love your videos! I learn a lot from watching them:) please keep making more video! Thanks :D
38 ATP is the number of ATP formed during the process of cellular respiration. 2 are formed during glycolysis and the other 36 are formed in the kreb's/citric acid cycle.
So helpful, thank you so much!!
This legit helped so much thank you
Really nice explanation. I love it.
damnit, i was going to learn passively but your intro actually got me to do what it said. it helped a lot :P
Thanks a lot you were a great help with my biology HW!

HOWEVER, if those 2 ADP molecules have already been used.. how does another 2 ADP's get used just before the pyruvate step?
Thanks so much, you made this crap understandable, if only bio lecture made any sense like you do I would actually enjoy biology
great video, thank you but i have one question... how did u get BPGAL out ot PGAL in 5:03? where does the second phosphate come from? i understand that aldehyde is oxidized to acid while reducing NAD to NADH but what about the phosphate?
Ur vids are amazing but your voice is SOOO soothing! You shld do ASMR vids on the side.. Seriously
Lol funny ASMR
lmaooo

Thanks brotha! You just saved my ass. My instructor barely speaks english and the department head writes the exams.
haha
Great video! Thank you! One question, why are the products of glycolysis always in twos?
Nice. Thanks for doing this! Liked
, & subbed.
you explain things well :) thank you
very helpful but this subject is sooo hard. test tomorrow. thank so much for the video!
Really like your voice, so clean.

When the NAD+ gets reduced into NADH I saw that an extra two (P) were added to the other end of the PGAL, does this mean when NAD+ gets reduced to NADH an extra two phosphates are added?
very well done, i understood it!! Keep it upp!!!! U are awesome
nice. adaquate pace and clear
U rock dude ...
Where does the two additional phosphates come from to make the extra two ATP's?(going from PGAL to BPGA)
I am a little confused about the net products, I thought that at the end of Glycolysis 2 H2O molecules are produced?
Thank you very much
hey I have a question...
Glycolysis also makes some H2O as its product right? And then the rest of H2O coming from the Electron Transport Chain.

thanks for every things
Thank you.
I love your intro!
