Very neat video and great attention to detail. You make a difference producing resources like this rather than yet another narrated powerpoint explaining glycolysis. Thank you!
One of the most helpful videos I’ve found. I would’ve loved to see more description of the exact mechanism of the chemical reactions that enable enzymes to do the things they do!
When hexokinase functions as a kinase (as stated in the name) which means it adds a phosphate. Any molecule that is phosphorylated (adding phosphate) has it done from the hydrogen atom attached to a hydroxyl group. So when phosphate is added it replaces the hydrogen that was on the oxygen atom. Hope this helped
It starts adjacent to the mitochondria, not in it, so it's technically in the cytoplasm. "Hexokinase II is also located at the mitochondria outer membrane so it can have direct access to ATP"
1. Glucose phosphorylated, forming glucose-6-phosphate. 2. Glucose-6-phosphate converted into its isomer, fructose-6-phosphate. 3. Fructose-6-phosphate phosphorylated again, forming fructose-1,6-biphosphate 4. Fructose-1,6-biphosphate cleaved in two, forming one molecule of dihydroxyacetone phosphate and one molecule of glyceraldehyde-3-phosphate. 5. Dihydroxyacetone phosphate converted into its isomer, glyceraldehyde-3-phosphate. Results of first phase: 2 molecules of glyceraldehyde-3-phosphate (G3P).
Wow! The sounds, the graphics, the explanation, is gold and extremely helpful!
Thank you!!!
Glad you enjoyed it!

Real life in action. This video helped me to understand the complex process like glycolysis. Thank you!
Amazing!! The visuals are so smooth and satisfying!
I'm glad you like it
This blew my mind! Thank you for this, it really helped me synthesize the information! Amazing visuals!

This is an amazing video. Can I ask where the Proton (H+) comes form in the first step involving the hexokinase enzyme?
I think it comes from the glucose molecule.

It's not a proton, it's a ion
Very nice this abimation, I can understand very well thanks 👍👍👍👍🤘🤘🤘🙏🙏🙏
wow, i can't express more emotions than WOW!
Nice 👍 sir thank you very much 🙏🙏
Thank you! Biology is beautiful.
Doesn't Glycolysis happen in the cytoplasm and not in the mitochondria?

@@biointeractive Thank you for clarifying
Interesante, por favor publicar traducido al español para difundir entre estudiantes. Gracias
Thank you.
You're welcome!

should the third enzyme be specified as PFK-1?
Two atp are used at step 1 and 3 and two atp is gained at step 7 and 10 , so i didn't get how any atp is being gained
Each 1,3-bisphosphoglycerate is used to generate 2 ATP (so four total) at steps 7 and 10, giving glycolysis as net gain of 2 ATP.
@@biointeractive thank you
Awesome
Cool visuals but couldve been explained better
Helpful
where is the source NAD+ and the pi
Either come from the electron transport chain or it can also come from lactac acid dehydrogenase
Good but the sound in the video behind explaining offfff
thank the saylor gods that i only have a five minute video today
