So apparently the 2009 online ADA is all corrected from the multiple mistakes that were found on the earlier versions and paper version.

Either way,, I took the test today, and in regards intracellular buffer; I put Phosphate,, but got it wrong, and answer should be bicarbonate?


Could someone please put the right facts down. Is it Phosphate or Bicarbonate?

 

[predental012]

Intracellular buffer = phosphate
Extracelllar (blood) buffer = bicarbonate

i had learned in biochemistry bicarb is a buffer, and is involved in secretions @ the proximal convoluted tubule.

It's a mistake, the answer is phosphate.
