What is required for osmosis to occur?
A) pressure gradient
B) solute pump
C) aquaporins
D) sodium-potassium pump
E) vesicles

Question

Quizplus · Accepted Answer

Osmosis is the movement of water molecules across a semi-permeable membrane, from an area of high concentration to an area of low concentration. Aquaporins are specialized channel proteins that facilitate the movement of water molecules through the membrane, allowing osmosis to occur.

Therefore, the presence of aquaporins is required for osmosis to occur. The other options listed (pressure gradient, solute pump, sodium-potassium pump, vesicles) do not directly facilitate the movement of water molecules across the membrane and are not necessary for osmosis.
