Decreased PCO2 (respiratory alkalosis) results in _____ HCO3- reabsorption

In the lumen of the collecting duct, NH3 and H+ form NH4+, which is trapped in the tubular fluid and excreted ("_____"))

If metabolic alkalosis is accompanied by ECF volume _____, the reabsorption of HCO3- increases, worsening the metabolic alkalosis

Renal compensation of respiratory alkalosis includes _____ excretion of fixed H+ as titratable acid and NH4+

Renal compensation of respiratory alkalosis includes _____ reabsorption of "new" HCO3-

In the proximal tubule, glutamate is ultimately metabolized to _____, which is reabsorbed

In the proximal tubule, **NH4+** (produced via glutamine metabolism) is secreted into the lumen via the _____ exchanger.

ECF volume contraction results in _____ HCO3- reabsorption

In _____ cells, CO2 is combined with H2O via the enzyme carbonic anhydrase, forming H2CO3
