Explanation / Answer

True

(The collecting duct can secrete hydrogen ions with a really high hydrogen ion concentration gradient if your body thinks its blood is too acidic. Therefore, acidic, or that is to say urine with low pH, will be excreted in that case. Conversely, if your body thinks it's a bit too alkaline, then the collecting duct can secrete bicarbonate, which is a base, into the collecting duct and therefore cause the urine to become more alkaline. In response to alkalosis, the kidneys may excrete more bicarbonate by decreasing hydrogen ion secretion from the tubular epithelial cells.

Bicarbonate ions, HCO3-, found in the filtrate, are essential to the bicarbonate buffer system, yet the cells of the tubule are not permeable to bicarbonate ions. The steps involved in supplying bicarbonate ions to the system are summarized below:
