Detailed explanation-1: -The PCT is responsible for reabsorbing most of the glucose, amino acids, and small peptides that enter the ultrafiltrate (Berry and Rector 1991). The PCT contains numerous secondary active, sodium-coupled transporters for glucose (SGLT2) and amino acids (Silbernagl and Gekle 2008; Silverman 2008).
Detailed explanation-2: -Glucose, amino acids, NaCl and other essential salts are reabsorbed in the second step of urine formation i.e Tubular Reabsorption. These essential substances are filtered from blood in the first step called glomerular filtration and are reabsorbed as they are vital for body function.
Detailed explanation-3: -Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride, and about 70% of the sodium reabsorption occurs here.
