The Filtrate in the Proximal Convoluted Tubule of the Human

Question

The filtrate in the proximal convoluted tubule of the human does not normally include
A)ions.
B)glucose.
C)plasma proteins.
D)amino acids.
E)dissolved gases.

Accepted Answer

The proximal convoluted tubule of the human kidney filters small molecules from the blood into urine, but plasma proteins are too large to pass through the filtration membrane and are therefore not found in the filtrate. Ions, glucose, amino acids, and dissolved gases are all normally present in the filtrate.
