1) Glucose and amino acids are completely reabsorb by symporters and facilitated diffusion from proximal convoluted tubule.
2) Water is reabsorb about 60-65% into blood by osmosis by proximal convoluted tubule.
3) Sodium ions are reabsorb about 60-65% into blood by sodium pump and symporters and antiporters in proximal convoluted tubule.
4) Potassium ions are reabsorb 65% into blood by simple diffusion in proximal convoluted tubule.
5) Urea is about 50% reabsorb into blood and variable secreted into urine in proximal convoluted tubule.
6) Bicarbonate ions are reabsorb about 80-90% into blood by simple diffusion.
7) hydrogen ions and ammonium ions are variable secreted from proximal convoluted tubule by anti-porters.
