A: PCT Normally about 65% of the filtered load of sodium and water, essentially all the filtered glucose and amino acids and a slightly lower percentage of filtered chloride are reabsorbed by the proximal tubule. The proximal tubules also secrete organic acids, bases and hydrogen ions into the tubular lumen.
