Question

Hello. Can someone please help me with answer these with a thorough explanation of what is going on? Thank you so much in advance!

What is the impact on Hb affinity and what state is present for Hb in each scenario?

(a) An increase in the pH of blood plasma from 7.2 to 7.6.

(b) An increase in the partial pressure of CO2 in the lungs from 2 kPa (normal) to 6 kPa (holding your breath).

(c) An increase in the BPG level from 5 mM (normal altitudes) to 8 mM (high altitudes).

(d) An increase in CO from 1.0 parts per million (ppm) in a normal indoor atmosphere to 30 ppm in a home that has a malfunctioning or leaking furnace.

Answer 1

The increase or decrease of the pH causes a displacement of the curve, which I show above this. And that the impulse of the CO2 pressure by the action of the carbonic anhydrase produces an increase of H+ that are those that are fixed to the hemoglobin diminish their affinity.
