Which factor does NOT influence the rate of facilitated diffusion?

Facilitated diffusion differs from simple diffusion in that it:

Choose odd one out w.r.t. facilitated diffusion.

What are the aquaporins in facilitated diffusion process?

    Consider the following statements and choose the correct answer

I.    Carrier proteins are needed by both facilitated diffusion and active transport and are sensitive to inhibitors that react with protein side chain

II.    Different types of proteins present in the membrane plays a major role in both active as well as passive transport

III.    The carrier proteins needed by facilitated and active transport are specific

IV.    There is no need of energy to pump molecule against a concentration in active transport

V.    Transport rate reaches to saturation point, when all the active proteins are used

Active transport

    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

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

In facilitated diffusion, the carrier protein:

Water channels are made up of how many different types of aquaporins?

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

These channels are made up of
