Ammonia is secreted into filtrate in which part of the nephron ?
Proximal convoluted tubule
Distal convoluted tubule
Loop of henle
Both a & b
During urine formation, the tubular cells secrete substances like H+,K+ and ammonia into the filtrate. Tubular secretion is also an important step in urine formation as it helps in the maintenance of ionic and acid base balance of body fluids.
Hydrogen is secreted in both PCT & DCT .
potassium is reabsorbed from PCT , but is secreted into filtrate in DCT.
Ammonia is secreted into filtrate in PCT.
Hence option B is correct.
