Rate limiting step in facilitated diffusion?
Correct Answer: Conformational change in transpoer
Description: Ans. is'b'i.e., Conformational change in transpoer(Ref: Essentials of membrane Biophysics p. 25I).The relative slowness of the rate constant for conformational change reorienting the Solute-unoccupied transpoer (Step-4) makes it the rate-limiting step in the process of facilitated diffusion.
