Answer to Question 1

ANS: C
When the CO2 is normal while the A is elevated, the PACO2 must be lower than normal. Like-wise, the PACO2 will fall if carbon dioxide production decreases or alveolar ventilation increases.

Answer to Question 2

ANS: C
The intracellular PO2 (approximately 5 mm Hg) provides the final gradient for oxygen (O2) diffu-sion into the cell.
