Q. Select the correct option in reference with the statements given below I. Facilitated diffusion cannot cause net transport II. Transport rate in case of facilitated diffusion never reaches to a maximum level III. Facilitated transport is selective to inhibition proteins IV. Concentration gradient is not required in case of facilitated diffusion
A) II and IV
B) I, II, III and IV
C) I and III
D) None of these
Explanation
Concentration gradient must already be present for molecules to diffuse even if facilitated by proteins. Transport rate in facilities diffusion reaches a maximum when all of the protein transporters are being used (saturation)
