WebThe proximal tubule is responsible for the reabsorption of the largest fraction of filtrate. It reabsorbs about 70% of filtered NaCl and water and 100% of the filtered glucose and amino acids. Reabsorption is a highly specific process that occurs through specific proteins located on the apical membrane of kidney tubule cells. Reabsorption of Web15% of the filtered water. Interestingly, the descending tubule is designed for water reabsorption while the ascending tubule is designed for NaCl reabsorption. Water reabsorption occurs through aquaporin channels type I. As the filtrate moves through the descending tubule the osmolarity will begin to increase because of the loss of water ...
