The only one that is not reabsorbed by the proximal convoluted tubule is ; C: Hydrogen Ions
The proximal convoluted tubule is an organ in the body that reabsorbs filtered glucose into the peritubular capillaries in a way that it is reabsorbed by the end of the proximal tubule.
Now, the proximal tubules reabsorbion is isosmotic and is usually about 65% of water, sodium, potassium and chloride, 100% of glucose, 100% amino acids, and 85-90% of bicarbonate.
Looking at the options, the only one that is not reabsorbed by the proximal convoluted tubule is Hydrogen Ions
The missing options are;
A: Potassium
B: Sodium Chloride
C: Hydrogen Ions
D: Urea
E: Water
