Question

Quizplus · Accepted Answer

Proteins are not directly involved in the elimination of hydrogen ions. The other choices (B, C, and D) all have some involvement in the elimination of hydrogen ions. Phosphate can buffer acid by binding to hydrogen ions, ammonia can react with hydrogen ions to form ammonium ions which can be excreted in urine, and bicarbonate can act as a buffer to neutralize excess acid by accepting hydrogen ions.
