When high levels of glucose enter the blood stream, insulin is released by beta cells in the pancreas. Insulin then initiates a number of signal pathways in specific muscle and fat cells. This takes a look at the signal pathway responsible for allowing those cells to rapidly increase their ability to uptake glucose from the blood stream.
This helped a lot - thank you! I'm a visual learner, and seeing everything laid out in a way I can see and in chronological order really does help.
Very nice illustration.
transporter for glucose in muscle and adipose tissue is GLUT4, but for brain is GLUT3. There are 12 glucose transporters encoded in the human genome.
that was really wonderful an exellent explication with amazing illustration.......... thank you so much
The video seems to show, in fat cells, three glucoses being converted to glycerol to provide the backbone of a single triacyglycerol molecule. Actually glycerol is formed from 1/2 of a glucose, a 3-carbon chunk.
My goodness...how/why do you guys do this for free? You all have saved me from countless Fs!
as bodoification said, the brain does not use GLUT4 (insulin dependent) receptors. It instead uses GLUT3 and GLUT1 (blood brain border). Therefore no insulin is required for glucose uptake into the brain or RBCs. GLUT 4 are only used in adipose (fat tissue), cardiac and striated muscle.

Thanks ND State. Some of the very best on YT.
Thank you
Did anybody else go, "aww" at the end when all the glucose came in?
I don't know why I did.
they do it for that warm, fuzzy feeling inside
This is amazing thank you so much
Beautiful!
I like when the vesicles fuse with the membrane :)
this is really resourceful. thanks.
This is really amazing.
that was beautiful
they made it more complicated!dang!!!
wicked cool
amazing
Sel alfa mensistesa, menyimpan, mensekresikan hormon glukagon (peptida) ketika kadar gula darah turun, glukagon menstimulasi hepar utk mengubah glikogen menjadi glukosa (glikogenolisis) yang akan meningkatkan kadar gula darah.
very nice!
Really very nice!:)
awesome
very nice
Same thought as jrg305. Are my brian cells fully or partly dependant on glut4? I think liver and brain cells have other mechanisms that are at least primarily responsible for uptake of insulin. If I'm correct then this video is in error @ 2:15-16.
I thought the brain wasn't dependent on Glut4 transporters...it's one of those tissues that requires glucose and insulin resistance there would mean death or increased use of ketones. Someone enlighten me on my perceived discrepancy.
I commented in Indonesian because my Indonesian to English translation is not as good as my English into Indonesian.
Saya berikan tanda "Suka" untuk video ini walaupun ada sejumlah kesalahan dan belum cukup dalam dan belum cukup lengkap, supaya ndsuvirtualcell memperbaruinya kelak.
Bagi orang-orang yang sekolah dasar, sekolah menengah pertama, dan sekolah menengah umum nya tidak bermutu betulan maka mengira ini tingkatan kuliah sehingga mereka harus balik ke sekolah-sekolah itu untuk betulin mutunya dan tentu saja ijazah kuliahnya dibatalkan. Tetapi bagi orang-orang yang bermutu betulan maka ini tak lebih dari SMU/SMK/Kursus bermutu betulan. Karena kalau ini tingkatan kuliah maka tentunya dicirikan oleh teori-teori bio kimia molekuler yang berciri kalkulus, atau pengetahuan semua ilmu yang maksimal. Saya tidak melihat teori-teori tersebut atau pengetahuan semua ilmu yang maksimal itu di video ini sehingga ini tak lebih dari SMU/SMK/Kursus bermutu betulan.
Just trying to warp my head around this. So for that final step, after PIP2 is phosphorylated, it phosphorylates another protein.
Is that Akt, which goes on to prevent the RAB interacting with the vesicles.?
is this a phosphonoisotide signalling pathway?
can do a vdo of cell signalling?
Hello! Have you thought about the Hamilton Diabetes Reversal Protocol? (search on google) I have heard some super things about the results in lowering Blood sugars and my brother in law got excellent resultsafter trying it.
Yo dis shit fire 🔥
Hej hej Lasse bo
You know, it will be hard for you to get credibility if you keep writing things like ''coz''...
Shame on you, its ATP not energy. Do better 🙄🙄🙄
Yet here you are writing “its” when it’s supposed to be it’s. YOU do better 🙄🙄🙄
