One of the most important functions of the cell membrane is the transport of molecules across it. Which of the following statements is/are true regarding its function?

(A) The membrane is permeable to all solute and solvent molecules present on either side of it.

(B) Movement of water across the membrane from higher to lower concentration by diffusion is known as osmosis.

(C)The nonpolar molecules pass through the polar lipid bilayer, through a carrier protein of the membrane.

(D) A few ions or molecules are transported across the membrane against their concentration gradient, in which ATP is utilised, e.g., Na+/K+ Pump
