Which of the following statements about passive transport is correct?
A
Passive transport operates independently of diffusion.
B
Passive transport operates independently of the concentrations of the moving solute.
C
In passive transport, solute movement stops when the solute concentration is the same on both sides of the membrane.
D
Passive transport does not occur in the human body.
E
Passive transport permits the solute to move in either direction, but the net movement of solute molecules occurs down the concentration gradient of the molecule.
