(b) in${{\text{O}}_{\text{2}}}^{\text{-}}$ deficient cells

With deficient supply of oxygen in the reactant side, the reaction will shift to the left. This is according to Le Chatelier's principle. The lack of oxygen in the reactant disturbs the equilibrium and will produce adequate amount of oxygen to maintain a new equilibrium.

Hence the reaction will shift to the left

(c)

During alkalosis, the$\left[{\text{H}}_3{\text{O}}^{+}\right]$ in blood decreases. With deficient$\left[{\text{H}}_3{\text{O}}^{+}\right]$ in the product, the reaction will shift to the right As the$\left[{\text{H}}_3{\text{O}}^{+}\right]$ increase during the shift in reaction, the$\left[{\text{HbO}}_2\right]$ also increases. The oxygen binds to the haemoglobin and will be ready for transport.

Therefore during alkalosis, it is easier for Hb to transport oxygen

(d)

During acidosis, the$\left[{\text{H}}_3{\text{O}}^{+}\right]$ in blood increases. With abundant$\left[{\text{H}}_3{\text{O}}^{+}\right]$ in the product, the reaction will shift to the left. As the$\left[{\text{H}}_3{\text{O}}^{+}\right]$ is being consumed during the shift in reaction to produce the left side products,$\left[{\text{HbO}}_2\right]$ also increases. The oxygen that binds to the hemoglobin for transport will decrease.

Therefore during acidosis, it is more difficult for Hb to transport oxygen.
