As I was taking the 2009 DAT yesterday, I chose "Phosphate" as the major intracellular buffer. The answer in the back said it was "Bicarbontae." However, today I was taking a Bootcamp test, and they said that bicarbonate was the major extracellular buffer, and that phosphate was the main intracellular buffer. Who is right??

The 2009 DAT has some mistakes in their answer key. Here are at least some of the corrections: http://forums.studentdoctor.net/threads/2009-dat-sample-test-errors-confirmed-by-ada.828825/
As for the buffers, bicarbonate should be the main extracellular buffer and I believe phosphate would be the intracellular.
