H+ and HCO3-. 1  The secretion of H+ in this section of the nephron is mainly a result of the Na+/H+ antiporter in the apical membrane using secondary active transport. 2  HCO3- is reabsorbed here in a different way to other substances. 3  Link to Article.
Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: 1  Specialized proteins called transporters are located on the membranes of the various cells of the nephron. 2  These transporters grab the small molecules from the filtrate as it flows by them.wo major factors affect the reabsorption process: 1  Concentration of small molecules in the filtrate-the higher the concentration, the more molecules can be reabsorbed.
