<unk>  is the part of renal physiology that deals with the retrieval of filtered<unk> s, preventing them from disappearing from the body through the urine. Almost all reabsorption takes place in the proximal tubule. Only ~1% is left in the final urine. The<unk> s cross the apical membrane by endocytosis. They are subsequently degraded in lysosomes. The remaining free amino acids are transported across the basolateral membrane by amino acid transporters.
