Question

Consider the equilibria:

1. $Hb\left(aq\right)+4O_2\left(g\right)\rightleftharpoons Hb\left(O_2{)}_4\right(aq);K_{c_1}$
2. $Hb\left(aq\right)+4CO\left(g\right)\rightleftharpoons Hb\left(CO{)}_4\right(aq);K_{c_2}$

(Hb) = Haemoglobin in Blood)

Identify the correct statement.

• A. at higher altitudes, equilibria 1 shifts towards right
• B. carbon monoxide poisoning makes the face of affected person look plate
• C. $K_{C_1}>K_{C_2}$
• D. people living on hills have more haemoglobin in their body than people living on plains

Answer 1

The correct option is D people living on hills have more haemoglobin in their body than people living on plains

As one climbs higher away from the mean sea level, the atmospheric concentration decreases, and therefore the amount of oxygen available proportionately decreases. In an effort to take in as much oxygen is available to us, the human body increases the number of RBCs in the system, which also would reflect in a higher haemoglobin count for such people.

Hence, people living on hills have more haemoglobin in their body than people living on plains.

So, option D is correct.
