Substance Q moves from the glomerular plasma to Bowman’s space without restriction. In the proximal tubule, Q binds to Na+ coupled transporter and crosses the luminal membrane. Q diffuses through the cytoplasm of the renal cell and is translocated to the interstitium via a facilitated diffusion transporter. With the given information, what can be concluded about the renal processing of substance Q?
