Q

Acid Base Balance: How is H+ secreted in the Kidneys

A

Late DCT:

Intercalated cell A:

  • H+ ATPase
  • K/H ATPase

However this is not sufficient on its own so you need: URINARY BUFFERS- as both below processes occur HCO3- is made and being added to blood

Phospahte:

(I think anywhere this can happen)

  • Na/ H exchanger (Na in and H out)
  • NaHPO4- combines with H+

Ammonia:

  • In PCT Glutamine synthesied to form NH4+
  • In CCT: NH3 secreted. H+ATPase secretes H+ which combine to make NH4+
