Therefore, oxygen - haemoglobin curve for fetal haemoglobin will appear on the left side. Oxygen dissociation curve for all the three terms: Hope this will help u........ Answer link WebSo in an acidic environment, this curve for any level of oxygen partial pressure or any amount of oxygen, we're going to have less bound hemoglobin. Let me do that in a different color. So then the curve would look like this. The saturation curve will look like this. So this is an acidic environment. Maybe there's some carbon dioxide right here.

WebJul 16, 2024 · Haemoglobin reaches 50% saturation when the partial pressure of oxygen reaches about 28 mm Hg. Now partial pressure had to be increased by about 70 mm Hg for haemoglobin to reach maximum saturation. If haemoglobin is a cooperative molecule, once haemoglobin reaches 50% saturation it should be easier to attain ~100% saturation. WebInstead, oxygen binding to myoglobin obeys a simple saturation equation with half-maximal saturation at about 5 mmHg (see Figure 6.4.4 ). It has two functions in muscle: it stores …
