AS Biology - Carbon dioxide transport in red blood cells (OCR A Chapter 8.4)

Рет қаралды 70,220

4 жыл бұрын

Carbon dioxide can be transported in three ways: dissolved in plasma, bind to haemoglobin to make carbaminohaemoglobin, or most commonly, be converted to hydrogen carbonate ions. This maintains the steep concentration gradient between the red blood cells and the plasma/tissue fluid/cells, which allows more carbon dioxide to diffuse into the red blood cells and be removed from the organs efficiently. This video will cover the mechanism of how it is done.

Thank you so much!! So does it mean after the whole process is reversed, the oxygen will bind with the haemoglobin that was dissociated from HHB?

@BioRach 3 жыл бұрын

Absolutely! And this actually explains the Bohr shift on how the haemoglobin's affinity for oxygen changes depending on the carbon dioxide concentration in different tissues/organs! :D see my other video on the Bohr shift!

Thank you so much for this video!!! One question though, what is the difference between plasma and tissue fluid?

@BioRach 10 ай бұрын

Plasma is the liquid in blood. Tissue fluid is outside of blood vessels and surrounding the cells.

Question - I know what you said is correct but I'd love if you could clarify why: why do the chlorine ions diffuse out of the erythrocytes, because I naturally would have thought the acidic hydrogen carbonic ions are 'used up' when they react and therefore the charge would be the same as before the hydrogen carbonate ions diffused back in? Thank you, I found this video very helpful :)

@BioRach 4 жыл бұрын

Yes, the concentrations of CO2, H+ and HCO3- within the red blood cells (RBC) will affect how much of this chloride shift occurs, but to put it in simpler terms... The point of chloride shift is to move the HCO3- ions out to the plasma, so to maintain the concentration gradient between RBC and the tissue fluid, to enable more CO2 to be converted into HCO3- form to be transported. The idea is to make it so as much CO2 can be transported away from the respiring tissues as possible. However to move the HCO3- ions out of the RBC and into the plasma, it requires a transport protein as charged ions normally cannot diffuse across the plasma membrane... And this transport protein is a cotransporter, meaning it'll only work if it also moves something in the opposite direction (kind of like the Na+/K+ pumps in active transport). And this "opposite" molecule is the chloride ions! In other words, in order for the transport protein to move HCO3- out, it also needs to move Cl- in, and vice versa. The exchange is on an one in, one out basis. Hope that makes sense? I hope that clears it up! And thanks for watching! :D
