Answer to Question 1

ANS: B
2,3-BPG plays a critical role in the effective transport of oxygen to tissue. It is produced via a shunt off of the EMP; elevations in 2,3-BPG are seen in a number of situations such as anemia. Elevated levels result in more effective delivery of oxygen to tissue. None of the other pathways or systems listed play a role in the way oxygen is delivered to tissue.

Answer to Question 2

ANS: A
A net gain of two molecules of ATP occurs for every molecule of glucose metabolized via the EMP. When the 2,3-BPG shunt off of the EMP pathway is taken, no net gain of ATP occurs. No energy is generated via the hexose monophosphate pathway. The methemoglobin reductase reaction reduces methemoglobin, the oxidized form of hemoglobin, to its reduced functional form and does not generate energy.
