Maximum potassium reabsorption occurs in-: (A) Proximal convoluted tubule, (B) Distal convoluted tubule, (C) Cortical collecting duct, (D) Medullary collecting duct
Answer is A. Ans. is 'a' i.e., Proximal convoluted tubule * Most of the solutes and water are maximally absorbed in proximal tubulei) 60-70% of Na+ is reabsorbed along with 60-70% of Clii) 60-70% of K+ is reabsorbediii) 60-70% of water is reabsorbediv) All the (100%) glucose and amino-acids are absorbedv) About 80-90% of bicarbonate is reabsorbedvi) 40-50% of urea is reabsorbed
