Question

Medal and fan
Describe what happens in the lungs, where the partial pressures of oxygen gas is high. Then, describe what happens when the blood travels to the tissue, where oxygen levels are low. Be sure to include the equilibrium constant expressions in your analysis.

Thanks(:

Answer 1

woah i can tell you 'biologically' what happens

Answer 2

O2+Hb --> HbO2 this is from lungs to RBC
from RBC to tissues
HbO2+CO2--->HbCO2 + O2

Answer 3

How does the reverse reaction happen?

Answer 4

well when O2 in lungs is in high conc than in RBCs in capillaries, then it diffuses out thus O2+Hb --> HbO2
when blood travels to the tissues
tissues use O2 in their cells and have waste CO2 thus conc of O2 in the tissue will be low while in blood it'll be high so O2 from blood diffuses to tissue HbO2+CO2--->HbCO2 + O2


since these reactions happen simultaneously
when RBC is near lungs it has to have high conc of CO2 in it So that O2 from lungs diffuse to it
so you can make it as equilibrium like this


\[HbCO _{2} + O _{2} \leftarrow \rightarrow HbO _{2} + CO _{2}\]

Answer 5

That makes total sense, thankyou(:

Answer 6

or so i guess

Answer 7

lol okay no problem i hope im not making mistake

Answer 8

I don't think you are. It makes sense to me.

Answer 9

good then :D

Answer 10

right side happens in tissue and left side happens in lungs
