Detailed explanation-1: -So, the correct answer is ‘Amino acids’.
Detailed explanation-2: -Selective reabsorption takes place in the proximal convoluted tubule (PCT) of the kidney. It is the process by which certain substances that are required by the body (such as glucose, amino acids, vitamins and water) but have been filtered out of the blood during ultrafiltration, are reabsorbed.
Detailed explanation-3: -Glucose, amino acids, salts and high amount of water are reabsorbed in the nephron during the second step of urine formation, i.e., the selective reabsorption.
Detailed explanation-4: -Active transport is the key to the reabsorptive processes in the proximal tubule. Glucose and amino acids are reabsorbed across the apical membrane of the proximal tubule by sodium-coupled secondary active transport.
