Q. What is facilitated diffusion and active transport ?

The following list indicates certain molecules/ions and their mechanism of transport across the cell membrane. Determine the correct pair(s) from the list.

I. Diffusion - $N a^{+}$

II. Active transport - Amino acids

III. Osmosis - Water

IV. Facilitated diffusion - Glucose

Q. Facilitated diffusion can be differentiated from active transport except

Assertion: Both facilitated diffusion and active transport are mediated through membrane proteins.

Reason: Only active transport is selective in action.
