I own you thousands of bucks, that my parents have been paying to teachers whose teaching doesn't make sense. Thank you so much
MCAT note:
1) no protein digestion in mouth
2) protein digestion in stomach: parietal cells rel HCL; chief cells rel pepsinogen (zymogen, turns into active pepsin in presence of acid); g cells rel gastrin (+hcl & pepsinogen rel, and - gastric motility)
3) chyme in duodenum -/> CCK rel (cuz fat in chyme) and secretin rel (cuz acid in chyme). cck -> acinar cells of pancreas -> rel digestive enzymes (ex = trypsinogen, procarboxypeptidase a and b, chymotrypsinogen, proelastase) -> trypsinogen act by enterokinase in duodenum --> trypsin activates other rel digestive enzymes -> AAs, di and tripeptides. secretin -> acinar cells of pancrease -> rel h20 (helps proteases) and hco3- (stabilizes ph).
4) brush border enzyme at enterocyte (dipeptidase and aminopeptidase) --> AAs, di and tripeptides
5) apical Na+/H+ antiporter brings Na+ down conc gradient into enterocyte and brings peptides along with it while pushing h+ into lumen. na+/k+ atpase on basolateral side shuttls na+ out of the enterocyte to maintain na+ concentration gradient.
6) peptidase in enterocyte yield AAs
7) AAs -> hepatic portal vein -> liver (protein synthesis and AA uptake)
Thank you 🙏🙏
this video taught me more in 42 minutes than my professors do in the entire year. LOVE THIS CHANNEL
I was doing cardio on a treadmill while focusing on this tutorial at the mean time. Surely the most physically & academically productive 42mins I have experienced.
I think I'm in love with your brain, PLEASE DON'T STOP POSTING THESE VIDEOS

Just wanna say that these videos are a gem. Although you don’t get millions of views, the thousands of people that do watch them appreciate them sooooooo much. Thank you
Absolutely amazing. You, Sir, are one SUPER HUMAN and always leave me speechless on how easy you make things look like. Thank you endlessly!
These videos are fantastic. I’m not the only teacher who watches your videos for inspiration and to learn a few things myself. Thank you!
Oh man, you are so good at explaining stuff and drawing them out. Wish you were every subject lecturer at my uni :D

If I had this guy as my teacher I would be a doctor by now.
Thanks for your videos ❤️
The most underrated channel.
Thanks a lot
Very easy approach
I have so many questions: First, who are you and how did you get this good? Why do you look so young? Where were you when I was failing biology like 35 years ago? Why am I watching and enjoying this so much? Why is there so much chemistry in biology? How can you hold that much info in your brain?.. And why do I feel sooo dumb all of a sudden. ? So many questions and one hell of a learning ride.
amazing man , amazing
It's very helpful for me thank you
asmmmm I just love ur understanding skills
