Answer to Question 1

ANS: C
Catabolism of proteins continually produces fixed (nonvolatile) acids such as sulfuric and phos-phoric acids.

Answer to Question 2

ANS: B
The H+ of fixed acids can be buffered by HCO3 ions and converted to CO2 and H2O (see the previous reaction); the CO2 thus formed is eliminated in exhaled gas.
