Accepted Answer

A) True 
 B)False

Question 19

How is the renal tubule excretion of ammonia involved in maintaining the acid-base balance?

Accepted Answer

A)  An increase in blood pH accelerates tubule excretion of both hydrogen and ammonia. A decrease in blood pH produces the opposite effects, thus maintaining pH balance.
B)  A decrease in blood pH accelerates tubule excretion of both hydrogen and ammonia. An increase in blood pH produces the opposite effects, thus maintaining pH balance.
C)  Renal tubule excretion of ammonia causes the combining of hydrogen to form ammonium ions that decrease the blood bicarbonate buffer pair ratio.
D)  Ammonia excreted by renal tubules has no effect on acid-base balance.
