Very well explanation but I find some little confusing at 2:51, in the part of co2 + h2o and carbonic anhydrase then it forms carbonic acid. Carbonic anhydrase is an enzyme and it speed up and dissociates the h2co3 into hco3 and h+
A little confused by when you said , if we increase OH- , then if the balance shifts to the right. Even though more H+ is formed, there is also formation of more HCO- , so wouldn't that amount to no change ?
Hi! The kidneys work along with the lungs in regulation. From how I understand it, when the pH increases, the kidneys are going to keep the H+ ions while they get rid of more HCO3- ions. So they’re already removing the bicarbonate trying to bring the pH back up, and it compensates for the bicarb that’s being formed. I hope that was helpful! 😊
I have studied in school of medicine, or university long ago that we get energy from glucose through Kreb's cycle & electrone transport chain. yet i have red in an american book, giving a short hint that we get energy through citric acid cycle. i know there are alternative ways to get energy like lipids, protien catabolism, or keto-acids in starvation..... however i have forgetten the biochemistry details. all i ask is is it an onother name for kreb's cycle, i mean the citric acid cycle ?
Please can anyone explain why pH changes with PCO2 changes, as from the equation H+ and HCO3- are produced at a 1:1 ratio, and given that HCO3- buffers any H+ that is produced, forming H2CO3, wouldn’t [H+] and pH stay the same? (Not saying this is true - this is my question and what I’m trying to understand!). How can H+ concentration change if for every single H+ that is produced there is also one HCO3- produced that would buffer it to form H2CO3? Please I would be so grateful for an answer to this question, thank you so much!
5 years into medical school and all these concepts where very disorganised in my head. Thank you so much.
Thank you so much ma'am 😌 i gonna watch all your videos...i found it really helpful ☺️ thank you once again
oh my god so good u cleared my concepts about buffer mechanism thank you so much 💜💙
thank you so much for this succinct and straight to the point video
Wow Thank you sooo much, this is exactly what I needed
Our guru ,Suhas and vijay loves you ❤❤❤❤❤❤❤❤🎉🎉🎉🎉
It's the best❤❤❤
thank you so much!! your videos help me a lot.
this is fantastic, thank you!
bro this is actually amazing
Wow this is very good ❤
You are just phenomenal 😢❤where have you been all my life
The best video on biological buffers...
A small correction....it is Hasselbalch, not Hasselbach. Everything else was awesome...
Thanks for catching that! ✨
You're welcome! Please keep creating awesome content! ✨
Nice explanation 👌👌👍🏽
Crisp explanation!😊
Thank you
Thank you so much 💛
Good video!
Amazing ❤️🔥
Can you please upload GIT EMBRYOLOGY... please
tremendous explanation!
amazinggg keep goingg
Thanks,amazing

So?
i really like your all lecture. please make more videos on usmle step 1 and step 2. thank you so much mam.
Perfect. Which drawing program do you use? Thank you.

Awesome explanation 👍
I love this... ma'am can u plz upload pulmonary ventilation (resp. system)??🙏🙏

I also have the same question?
Thank you very much I am a arab girl and l understand you thanks thanks thanks❤❤❤
Thank you so much for your great video that help me alot! ❤️❤️
How can l gat this note
very helpful mam keepit up
Ty
Must be very nais
I'm in gen chem and was just looking for an explanation of buffers lmao
.
Have an exam today😂
this video is really poorly done.
