Solution
The correct option is C Proximal convoluted tubule
The most essential substances in the filtrate are reabsorbed in the first half of the proximal convoluted tubule (early proximal tubule). These include glucose, amino acids, phosphate, lactate and citrate, which “piggy-back” on sodium co-transporters (membrane proteins that link the movement of two or more specific solutes together) that move sodium down its electrochemical gradient into tubule epithelial cells. For this to continue, the sodium gradient must be maintained, which means sodium cannot be allowed to build up inside the epithelial cells of the proximal tubule wall. So, the correct option is 'Proximal convoluted tubule'.
