Substances secreted by active transport into the filtrate in the distal convoluted tubule:
K+ ions: Potassium ions are mainly reabsorbed in the proximal convoluted tubule and the thick ascending limb of the loop of Henle. In the distal convoluted tubule, potassium ions can be secreted into the filtrate.
Creatinine: Creatinine is a waste product generated from the breakdown of creatine phosphate in muscles. It is not reabsorbed by the nephron and is primarily excreted by filtration in the glomerulus and secretion in the distal convoluted tubule.
Urea: Urea is a waste product formed in the liver during protein metabolism. It is primarily reabsorbed in the proximal convoluted tubule but can also be secreted into the filtrate in the distal convoluted tubule.
HCO3- ions: Bicarbonate ions are primarily reabsorbed in the proximal convoluted tubule and the thick ascending limb of the loop of Henle. In the distal convoluted tubule, hydrogen ions are secreted into the filtrate, which combines with bicarbonate ions to form carbonic acid.
Therefore, the correct answer is option D: Only a and d. Potassium ions and bicarbonate ions are secreted by active transport into the filtrate in the distal convoluted tubule.
