A mutation in an aquaporin gene results in a non-functional protein. Which of the following cellular processes would be MOST directly affected?

Facilitated diffusion involves?

Which characteristic distinguishes facilitated diffusion from simple diffusion across a biological membrane?

Which of the following is not correct regarding carrier molecules, involved in facilitated diffusion?

    Water channels are possessed by a membrane to facilitate the movement of hydrophilic substances.

These channels are made up of

If two molecules A & B move in the same direction. This movement can be called

If two molecules A & B move in the same direction. This movement can be called

Facilitated diffusion does not require/show

    Read the following statements regarding porins and select the correct option given below

I.    Porins are transport proteins

II.    Channel proteins are a type of transport protein, which are usually gated

III.    Carrier protein binds the particular solute to be transported

IV.    Particular solute is delivered to the other side of the membrane by carrier proteins

Certain integral membrane proteins facilitate the diffusion of molecules across the membrane without directly binding to the transported molecule. These proteins create a continuous aqueous pathway through the lipid bilayer. Which of the following is the BEST example of such facilitated diffusion?

Facilitated diffusion
