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! 😊
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!
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+
