  1. Under normal conditions which one is completely reabsorbed in the renal tubule?
    1. Urea
    2. Uric acid
    3. Salts
    4. Glucose
Correct Option: D

The cells of Proximal Convoluted Tubule (PCT) reabsorb entire glucose, amino acids, most of the inorganic ions (Na+, K+, Cl-), most of the water as well as some urea. Glucose is reabsorbed actively and most effectively.
