WebKidney Reabsorption. Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: Specialized proteins called transporters are located on the membranes of the various cells of the nephron. These transporters grab the small molecules from the filtrate as it flows by them. Web1. Reabsorption moves filtered solutes from the renal tubule to the blood. 2. Reabsorption of solutes occurs predominantly within the PCT. 3. Most solutes cross the epithelium in a …
