Q

najpomembnejši puferski sistemi v organizmu

A
  • bikarbonatni pufer
  • fosfatni pufer
  • raztopina proteinov

v krvi: prisotni vsi trije
1. bikarbonatni pufer (največ)
2. plazemski proteini
3. hemmoglobin

nizka koncentracija fosfata - ne doprinese k vzdrževanju pH v krvi; pomemben za vzdrževanje pH v urinu
