Hemoglobin ( Hb ) is a blood protein that is responsible for transporting oxygen. It can exist in the protonated form as HbH + . The binding of oxygen can be represented by the simplified equation: HbH + + O 2 ⇄ HbO 2 + H + (a) What form of hemoglobin is favored in the lungs where oxygen concentration is highest? (b) In body tissues, where the cells release carbon dioxide produced by metabolism , the blood is more acidic due to the formation of carbonic acid. What form of hemoglobin is favored under this condition? (c) When a person hyperventilates, the concentration of CO, in his or her blood decreases. How does this action affect the given equilibrium? Frequently a person who is hyperventilating is advised to breathe into a paper bag. Why does this action help the individual?

Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.
Complete the reaction in the drawing area below by adding the major products to the right-hand side.
If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead.
Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule
to represent each pair of enantiomers, using line bonds at the chiral center.

Some notes:
• Draw only the major product, or products. You can draw them in any arrangement you like.
• Be sure to use wedge and dash bonds where necessary, for example to distinguish between major products that are enantiomers.
• If there are no products, just check the box under the drawing area.
