Neurogenesis in the mammalian brain
The human brain contains ~86 billion neurons and an equal number of glial cells. The majority of these cells are generated between 5 weeks and 8 months of prenatal development. This video walks through the process of neural stem cells and neural proliferation.

Insulin PI3K Akt signaling pathway
Просмотров 4,2 тыс.3 года назад
The video begins with an overview of the role of insulin in regulating blood sugar levels. Then it reviews the structure and activation of the insulin receptor, and the IRS-PI3K-Akt pathway. It shows how Akt can lead to insertion of GLUT4 vesicles into membranes, and then looks at the metabolic actions in liver and fat cells.

This video walks through the GPCR, G alpha s, adenylate cyclase signaling pathway. It examines the cellular events for each step. The video concludes with a look at how the pathway is inactivated and the role of arrestins in cell signaling.
GPCR IP3 DAG pathway
Просмотров 7 тыс.4 года назад
A walk-through the g protein coupled IP3 DAG pathway. This is one of the common GPCR linked signaling pathways, and the video illustrates each of the players: how GPCRs activate Galpha subunits; how Galpha activates phospholipase C (PLC), how IP3 and DAG are produced, and their targets in the cell. Video includes two examples of this pathway is specific cell types degranulation of mast cells an...

You are AMAZING. I’m so glad I found your channel! Thanks for this excellent explanation.
lifesaver thank you! brilliant teaching of these pathways
Fantastic and concise - thank you so much
Very nicely explained
Thank you
🎉
...what was the answer to that question at the end..? 👉👈
Heyy. Idk if u'll see this. but, I really hope you keep making these videos.
This is the best explanation on RUclips for this!!! 🎉❤
So interesting, thank you from the psychology department / University of Basel, Switzerland
many thanks for this mind-blowing and educational video!
Incredibly interesting!!!
loved your lecture. Particularly liked the way you combined scientific work done in the field with your explanation. Really hope to see more videos from you.
Thank you very much
Thanks a lot for making biochemistry enjoyable !!
great video.
Very helpful..
this was so so helpfiul! thank you!
Best video on this topic! I have so many places and I understood nothing, thank God I found you, my exam is tomorrow and definitely this question will be there. So you have helped me to get closer to a Distinction in BSc Chemistry
this was so helpful, saved me for my midsem
👌👌👌👌
Excellent video
Thank you so much for this video
Great video thanks
This is one if the most useful videos i have ever come up on RUclips.
WOW! THANK YOOUUUU!
Thank you very much. I've watched several videos on the subject of lineweaver-burk plots, yet you are the first one that actually tells me how to fill in the graph by translating the [S] and V into 1/[S] and 1/[V]. I had a hunch that this would be the answer, but no examples. Greetings from the Netherlands
🙏🙏🙏
This helped me a lot!! Is it possible to get an answer key for the last questions??
🙏🙏🙏🙏🙏♥️
🙏♥️
❤ great video ,animation and explanation…..thank you :)
Great video. Thank you very much💞
This was REALLY helpful! Thank you so so much!
You can explain very very well sussanah. Keep up your great work❤ Thank you so much
Amazing
so fuckin helpful
It's been a week trying to study this and finally found someone that explained it flawlessly! Truly Thank you!
The fact that there are no more follow up videos after this is a crime against humanity
Thanks so much for these videos!!
I''ve been struggling for weeks to understand this. thanks for this video. very helpful.. :)
Amazing
so helpful! thanks!
Very effective 🎉
The calcium is responsible for the fusion and forming complex with t-snares or the calcium is responsible for immobilizing the vesicles by interaction with synapsin and releasing vesicles from cytoskeleton of cell . Is calcium responsible for both or is one of them wrong
Thank you very much! This lecture was very helpful.
❤❤❤
Nice lecture but a small query: at 11:01 through 12:39 do you mean cell does not inhibit malic enzyme........As can be seen from the M-M curve aspartate increased the malic enzyme activity (isn't it non-inhibiting?). But, what you are saying from 11:01 to last, negates all about the aspartate activity.......Did I miss something? I wish to know if I am correct or wrong. Now I am more confused.
You are right. Aspartate is an activator and speeds up the rxn.I did mispeak there. Specifially -- the text at the top of the page at 11:25 should read, why would the cell want to activate malic enzyme when there is lots of aspartate. As far as why... we normally think about the TCA cycle as a simple cycle without the off/ on ramps that allow the cell to feed other substrates into the cycle and to take out intermediates to use for other rxns. If the cell has plenty of aspartate, then it can convert that aspartate into oxaloacetate and keep the TCA cycle running. That means the cell is free to redirect some of its malate in the side rxn catalazyed by malic enzyme. For example, the resulting pyruvate can be converted into several small amino acids (e.g., alanine) or used for other anabolic pathways.
I like the way you simplyfied the whole L-B plot.. Great stuff in a short video. Was potent and soundly put It had everything in a nutshell Kudos I appreciate your efforts and enthusiasm Best Vijay
Thank you very much. Excellent lecture
Great video, thanks for sharing :)
