Q. Compare the following processes of transport and choose the correct option [table] S. No. | Property | Facilitated Diffusion | Active Transport | Simple Diffusion ; I. | Highly specific | Yes it is selective | Yes | No ; II. | Energy as ATP | Yes | Yes | Yes ; III. | Saturation point is attached when all carrier protein are being used | Yes | No | Yes ; IV. | Require transport proteins | Yes | No | Yes [/table]
A) Only II
B) Only III
C) I, II, III and IV
D) Only I
Explanation
Transport processes, facilitated diffusion and active transport are selective and specific because cells are allowed to select substances for uptake. Facilitated diffusion does not support uphill transport of substances, does not support uphill transport of substances, does not require ATP energy and movement of transport proteins are present
