In the Body Hydrogen Ions Produced from the Reaction of Carbonic

In the body hydrogen ions produced from the reaction of carbonic anhydrase are transported into the lumen of the stomach via an ATP utilizing proton pump.The removal of hydrogen ions drives formation of bicarbonate ions and a concentration gradient is formed.Bicarbonate is transported out at the same time that chloride ions are transferred in.Based on this information,which of the following is FALSE?

A) The pump driving the driving the hydrogen ions into the lumen must undergo a conformational change.
B) The pump driving bicarbonate out and chloride in must be an antiport system.
C) The pump driving bicarbonate out and chloride in must require ATP directly.
D) The bicarbonate-chloride pump requires ATP indirectly.
E) The bicarbonate-chloride pump must require activity of the proton pump.
