Insulin 2: What is glucagon?

[@dreb4386]

I looooved this video. I’ve been staring at a textbook all day trying to figure out what all of this meant. You are doing the lords work. Thank you!!!!

[@JamesWalck]

FINALLY a concise, foundational explanation of the insulin / glucagon interplay that this diabetic engineer can understand.....AND REMEMBER. Thank you !!!!

[@Holbywan]

Such a great, simple explanation of this process!

[@johnx9318]

Excellent presentation and information - thanks.

[@josieb3238]

Very clear presentation. Thanks.

[@pattayaguideorg]

Best explanation on the subject!

[@solomonravichandran5284]

Wonderful explanation 🙌

[@goodnewsmusic.5638]

Nice one! Thanks a lot. God bless 🙏🏼

[@mrpush2532]

So what happens if say glucagon levels for some reason stay really high? Like alpha cell dysfunction? Could this cause high sugar levels?

[@mohammadriyaz8123]

fantastic sir....thanks for easy explanation

[@merithaligeon172]

Thank you😊

[@Judy874]

Thank you for a great explanation!

[@oliviaraymond8496]

My god thank you this is PERFECTLY explained with the all picture in mind 😊

[@holyhellal]

fantastic explanation ,,,well done

[@jack23907]

wonderful explanation :)

[@RamRaj-if3ds]

Best explanation for me so far..tc

[@TheSweetalchemist]

What causes cell blockage? What causes for the key (insulin) not to function?

[@nickloks]

The same thing that makes a non drinker get drunk off one glass of wine when the alcoholic needs the whole bottle. The human body adapts to too much of anything including hormones

[@lightbeingpontifex]

insulin resistance,,, the cells block insulin,,,

[@johanna6050]

The cells are so full of glucose that there's no more room, so they are resistant to the job that insulin is trying to do. The glucose, therefore, remains in the blood.

[@tval3183]

Firstly the cursor-drawing ability is impressive enough to distract from the actual content. Secondly, if caffeine increases blood glucose levels by presumably(?) activating glucagon production, where does the glucose come from in a person who doesn't eat much sugar? If there isn't much in the bloodstream to begin with, I have to assume that it's pulled out of the storage cells (muscle, liver, fat), but which ones? And what happens to it from there? I've known for a long time that too much caffeine makes me sleepy but I don't know why - or didn't until recently. This might partly explain things but still doesn't entirely make sense.

[@brunospasta]

Could you just eat glucagon as a supplement and that will make your body convert fat to glucose and you would loos weight? Or as a supplement during high intensity sport to get even more glucose and energy in your blood flow.

[@mprado4177]

Awesome! Thank you!

[@michaelhashimoto1650]

Omg. this is so clear!

[@lightbeingpontifex]

what is the cell that takes up the glucose,,,

[@nory7684]

All cells take up glucose for energy …

[@michaelohara6447]

thank you

[@JohnJones-zm3nb]

I under stood this

[@clairemurphy2363]

I'm pretty sure this process saved me the other day. I work in a hospital and developed hypo symptoms. They went away briefly but came back and before I had chance to check my sugar levels I was unable to speak and was experiencing palpitations and confusion. I sat down when I suddenly felt my body go limp. I couldn't respond. I couldn't move much but I could hear everything that was going on around me. They took bloods quickly and ran them but my sugar was 5.5 which surprised me. And I began to recover by myself. Thinking more and more I realised did my stores kick in releasing enough glucagon to convert back to glucose to pick my sugars up by itself? The doctors didn't appear any the wiser and said I fainted (I did not faint, as I had awareness)

[@Turbotomass]

is glucagon not produce by the liver? ??

[@litabelaqua]

No, you are confusing another process that takes place in the liver. Glucagon is a hormone produced in the pancreas alpha cells, insulin is a hormone created in the pancreas beta cells. Simply put Insulin puts glucose into the bodies cells and glucagon takes it out again

[@nory7684]

You mean glycogen…glucose is stored as glycogen in the liver…glucagon on the other hand is a hormone produced in the pancreas and when released in the blood, it’ll promote the release of glucose…meaning glycogen will turn back to glucose

[@TheHandsomeman]

Why are a lot of people with type 1 Diabetes, very thin?

[@NoName-bo6cu]

But if your diabetic and don't produce insulin.. won't you not store the glucose

[@gantz0949]

Gains & Gaming correct. Continuous High Blood glucose is bad especially on kidneys

[@siva5183]

The most beautifuly explained in the whole world..this what it should be.You are the maestro.So diabetic is about the balance of hormone of insulin and glucagon.maybe the pancrease lack of beta and alfa cell cycle,solution do intermediate fastind to get rid fat cells in the pancreas to have me cell cycle to balance the sugar in blood and brisk walk jogging and cycling to faster the process.

[@krishnagoli687]

nice wid

[@kraxmalism]

is the presenter left-handed? just checking my analytical skills )) PS. fantastic explanation, 100M likes from me

[@blackspirit808]

Ez

[@jaimelopez8921]

This presuppose that Cell theory is true.

[@leafdude69420]

Gluco gone 💀

[@Ridingthewaves305]

Brain cells do not require insulin to uptake glucose, because the brain and the liver don't use GLUT4 for importing glucose -.- Side note, brain cells will only tolerate glucose, the brain can not use other fuel sources such as fat and protein. Great video otherwise!!!

[@TheFogskum]

Todd Jones wrong, the brain can use ketones for energy.

[@extremerunner]

Ketones from fat can be used as energy in the brain

[@litabelaqua]

The brain prefers and will readily use ketones, in fact there is only ONE cell type in the body that can only run on glucose and that is the blood cell Erythrocytes, and in the absence of glucose the liver will provide sufficient glucose in the process of gluconeogenesis.

[@nory7684]

@@litabelaqua you wrong the brain will prefer glucose over ketones…in fact ketones are only used up when glucose levels are low
