7704.	To carry out metabolism, oxygen is taken up by hemoglobin (Hb) to form oxyhemoglobin (HbO2) according to the elementary reaction. Hb(aq)+O2(aq)k→HbO2(aq). The value of k is 2.0×106 M−1s−1 at 37 ∘C (body temperatures). For an average adult the concentrations of Hb and O2 in the blood at the lungs are 8.0×10−6 M and 1.5×10−6 M, respectively. The rate of formation of HbO2 increases to 1.6×10−4Ms−1 during an exercise to meet the demand of increased metabolism rate. Assuming the Hb concentration to remain same, what must the oxygen concentration be to sustain this rate of HbO2 formation? If the anser is 'X', then give the answer by multiplying 'X' with 106.
Answer» To carry out metabolism, oxygen is taken up by hemoglobin $(H b)$ to form oxyhemoglobin $(H b O_{2})$ according to the elementary reaction. $H b (a q) + O_{2} (a q) k \to H b O_{2} (a q)$ . The value of $k$ is $2.0 \times 10^{6} M^{- 1} s^{- 1}$ at $37^{\circ} C$ (body temperatures). For an average adult the concentrations of $H b$ and $O_{2}$ in the blood at the lungs are $8.0 \times 10^{- 6} M$ and $1.5 \times 10^{- 6} M$ , respectively. The rate of formation of $H b O_{2}$ increases to $1.6 \times 10^{- 4} M s^{- 1}$ during an exercise to meet the demand of increased metabolism rate. Assuming the $H b$ concentration to remain same, what must the oxygen concentration be to sustain this rate of $H b O_{2}$ formation? If the anser is 'X', then give the answer by multiplying 'X' with $10^{6}$ .
