Question

When an increase in hydrogen ions remains after one hour, this will lead to a(n) ________.

1) decrease in bicarbonate reabsorption in the kidneys
2) increased hydrogen reabsorption in the kidneys
3) increase in bicarbonate secretion in the kidneys
4) increase in hydrogen ion secretion from the kidneys
5) failure of the kidneys to filter any more hydrogen ions

Answer 1

An increase in hydrogen ions remaining after one hour leads to a decrease in bicarbonate reabsorption in the kidneys, resulting in a pH imbalance and acidosis.

Step-by-step explanation:

When an increase in hydrogen ions remains after one hour, this will lead to a decrease in bicarbonate reabsorption in the kidneys. The presence of excess hydrogen ions in the filtrate leads to a decrease in bicarbonate conversion into CO₂, resulting in less bicarbonate being conserved in the body. This can lead to a pH imbalance and acidosis.
