Couldnt get a hold of this concept until now ! You draw out and explain everything so well thanks

[@Viva-qd2bo]

Thank you for this, I'm going on a field trip to do some scientific problem solving and we were told that we needed to know this and you explain it so much better than the study paper!

[@shwanmustafa5366]

simple to understand. many thanks

[@rashad4566]

the best place to go for help
thanks

[@ravenholbrook2353]

Everything makes sense now. Thank you so much!

[@youtubec8563]

Start from 3:38 for how buffer works. Before tells important biology concepts

[@ayrasherjil4866]

Thank you

[@frffzn95]

Thanks

[@eliaslott6180]

Thank you! this helped so much!

[@nargeskalani2587]

So much better than my own professors. I appreciate your work.. thanks so much.. I learned so much from your videos.

[@jeebanamar6332]

Your explanation is just amazing.....
No more words to say

[@2ri315]

Thank you so much! It helped me a lot! :)

[@aaaaaaa6148]

Great video,thank you.!

[@piscesbaby9421]

Thanks so much for this video!! I was so lost in class.

[@justjesss9051]

Thanks for this video 😊

[@haymaalani7543]

perfect explanation

[@beeramdhanunjayareddy3386]

Easy explanation thanks 🙏

[@abdulrahmanezzedin8004]

that's actually great thanks 💙

[@anasalrasbi4669]

اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّد في الأَوَّلِينَ وَالآخِرِينَ، وَفِي الْمَلأِ الأَعْلَى إِلَى يَوْمِ الْدِّينِ.

[@Eva-fv8gf]

Thank u that was very helpful 🤍🤍🤍.

[@hau5548]

Thank you sir! I hope I can survive this semester. Biochem is killing me ಥ⌣ಥ

[@BeeS392]

Does anyone know what software he used to write stuff? I kinda like it and wanna try it out. Thank y'all!

[@shivanshdubey2571]

Excellent!!!!❤️❤️

[@anwaralanazi3835]

You are the best 💛💛💛💛

[@kayewilde8871]

I am enlightened. But still, after watching this explanation, make sure to read the book as well and then if it's still unclear, go back to this video. I'm sure you'll get it by then.

[@JA-xv3qp]

So now we know what it means when someone says you’re so basic.

[@whatevervlogs9663]

I’ll tell them my pH levels are just fine

[@umchileanyways_so]

help😭💀

[@chaikajpeg2842]

Thank you!!!!

[@abdulrahimalfahdi5099]

nice, cool ,one of the best .*)

[@esabkhan7901]

SHUKRIA

[@exymian1342]

So a way to simplify this even more than it is : If H ions increase in our blood,it is more likely to bond with Bicarbonate and make it Carbonic Acid thus making it not change the pH in our blood.
Am i correct ?

[@sukieyakie]

do the h+ come from the blood or are they present in the haemoglobin

[@hardwayCF]

What's the role of Plasma Proteins in the Blood Buffering process?

[@Maryjcorder]

A point I’m needing clarification on is this: if CO2 is elevated, it stimulates chemoreceptors and is blown off. But an elevation in CO2 will also shift the equation to the right? So which happens first and/or predominantly? The two concepts seem contradictory, but I know there is a piece I must be missing. Thank you.

[@anxietylies1419]

I need formulas to show when a base or acid is added to the buffer!

[@dydwjwkd1519]

i was about to give up chemistry at college untill i saw this video
thank u so much from south korea❤

[@manda4915]

extremely clear and concise, thank you :)

[@BrajbihariRaj]

amanda jipa nnk

[@starwarfan8342]

I still don't understand, what happens if you dump the base into blood?

[@Ali-kh1rs]

I never comment but this dude knows what he's doing. The best place to learn period.

[@dr.shubhamingle7848]

sir,, does this reaction happens inside a parietal cell or blood vessels itself...?

[@jeyhuntalibov9911]

Sir please answer my question: Did you explain blood buffer in this video?

[@miro1mimi]

It's always the same with their videos they talk too much and sometimes drift away from the main topic...

[@pietrolovisetti3476]

amazing

[@amnafadhil3872]

How we started dumping hydrogen ions in the blood?

[@willemmeiring7176]

So you're telling me if my blood's pH is above 7.35 I'm too basic?

[@SM-wp5bw]

I LOVE YOU SAL CAN I MAARRRYYY YOU

[@murraykriner9425]

Funny that so many advocates of why our daily fluid intake needs to be either more Alkaline or Acidic in nature to sell some lauded product. It would appear that they are over-stating something that the body will counteract on its own in time. Like we can magically enrich or deplete Hydrogen Ions at will by consuming some bottled item. This is most interesting in a world where people purchase more fluids than solid foods in hopes of attaining a greater standard of health without having to trouble themselves with having to cook, or eat out. People are so easily dupped to sip from the modern fountain of youth.

[@sharonchoudhary151]

[@checheapenteng-takyiako372]

The way I screamed “basic” before he said alkalosis😭😭😂💔

[@aseelmaher6611]

Does phosphoric acid act as buffer ?

[@zoezzzarko1117]

Yup

[@jacob476]

unfortunately, what everybody who doesnt actually understand the topic misses, is WHY free hydrogen ions are bad and why free co2 is bad

[@zoezzzarko1117]

Why are they bad?

[@DrFox-ub8st]

I'm gonna watch looney tunes now 💔😭

[@shamilabarkat5798]

Usually your videos are very helpful. This not so much. I still don’t understand.

[@nebularcore]

Stiiiillllllllll so confused. O.O
