The rate of osmosis across a cell membrane depends upon which of the f...

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The rate of osmosis is influenced by several factors:

I. Intracellular solute concentration: The concentration of solutes inside the cell affects the osmotic pressure and determines the direction and rate of water movement.

II. Extracellular solute concentration: The concentration of solutes outside the cell creates an osmotic gradient and influences the movement of water into or out of the cell.

III. Polarity of solutes: The polarity of solutes does not directly affect the rate of osmosis. Osmosis is primarily driven by the concentration gradient of solutes, not their polarity.

IV. Molecular weight of solutes: The molecular weight of solutes does not directly affect the rate of osmosis. Osmosis is driven by the concentration gradient rather than the size or weight of solute molecules.

V. The presence of aquaporins: Aquaporins are specialized channel proteins that facilitate the movement of water across the cell membrane. The presence of aquaporins can significantly increase the rate of osmosis by providing a pathway for water molecules to move more efficiently.

Option A correctly includes factors I, II, and V, which are the key determinants of the rate of osmosis across a cell membrane.
