We're going to be discussing hemoglobin and equilibrium. For this question. We have three situations. And in each of those situations, situations will decide which side of this equation of this chemical reaction is favorite and what product we're trying to get because of that situation. Okay, for our first question, let's go. This color first scenario, which form of hemoglobin that'll be either this for this one of those two is favored in the lungs in the lungs, which have high 02 concentration. So if I have high 02 concentration as I don't know ones, which side of this equation would be favored? Well, if we increase the concentration of 02 we will shift right. And the H B 02 would be favored the HBO to would be favored in the laws. Okay. And let me try to raise a couple of these. Sorry, it's not perfect, but I'm sure you figured out. Okay. Now for our second scenario, let's read what our second scenario eyes, um, be in body tissues. Cells are released releasing co two. So co two is released. Dream metabolism to tissues in the body. So you haven't You have a little excess CO two and then that's going to form. Um, the blood is gonna be a little bit more acidic here. What would be a tinge? More acidic. Because carbonic gas, it small amount of carbonic acid is formed, so we'll have a little bit higher acidity and which form of hemoglobin is favored. So which form of hemoglobin is favored under a city conditions which form I wrote arm again is favored for those acidic conditions. Okay, so in a city conditions this concentration will increase, shifting our equilibrium to the left. So the H B H plus will be favored in tissues with a higher concentration. Ah, higher acidity. Okay, lets see race again and look at our third and final scenario, and this one will do in green. So for 1/3 scenario, were asked when you hyperventilate when her better person hyperventilates the concentration of co two, he goes down the CEO to concentration, and I was 302 Concentration decreases. So Theo to decreases. How does this affect the above equilibrium? So what will the shift b if the she c 02 decreases co two decreases? Um, that's gonna be like this is gonna shipped us to the right. If the sheer Theo to decreases, it means that this is going to decrease. This will shift the reaction to the right so it'll shift right. And then this has another piece for the question. When you are hyperventilating, sometimes you're told to breathe into a paper bag. And why would that help? Well, your equilibrium is shifting to the right because this is the concentration, the acidity. It's going to be tied up with your H plus us. If you breathe into a paper bag, you're gonna be breathing in more CO two. And if you breathe in more CO two, it's going to increase this concentration and shipped this concentration back to the left. That's it.
