Question

PLEASE HELP ME!!!!!!!!!!

Answer 1

Co2 diffuses into red blood cells down their concentration gradient. Here, the co2 reacts with water in the cytoplasm of the red blood cell with the help of the enzyme carbonic anhydrase to make carbonic acid (H2CO3). The carbonic acid then dissociates into H+ and hydrogen carbonate ions. The H+ ions binds with R-groups in haemoglobin in the red blood cell to make the compound carbaminohaemoglobin. The hydrogen carbonate ions leave the red blood cell and diffuse into the blood plasma whilst chloride ions move into the red blood cell (chloride shift) to maintain electrochemical balance.

Ik it's a lot but I hope it helped. I have a biology exam tomorrow and I also need to remember this haha
