Question

A person who has been a smoker and has a low oxygen blood saturation uses an oxygen tank for supplemental oxygen. The following equation depicts oxygen binding with hemoglobin:

Hb(aq)+O2(g)HbO2(aq)

Answer the following questions to describe what happens when oxygen is first supplied.

Part A: What is the stress on the equilibrium of the reaction between oxygen and hemoglobin?

A: The oxygen concentration is decreased

B: The oxygen concentration is increased

C: The HbO2 concentration is decreased

D: The hemoglobin concentration is increased

Part B

In what direction does the hemoglobin equilibrium shift?

A: The equilibrium shifts in the direction of the reactants

B: The equilibrium shifts in the direction of the products

C: The equilibrium does not change

Explanation / Answer

B: The oxygen concentration is increased

Part B

Hb(aq)+O2(g)HbO2(aq)

concentration of oxygen increases at reactant side the equilibrium shift to products side.

B: The equilibrium shifts in the direction of the products
