Imagine a small syntyetic vesicle made from pure phospholipids enclosing an interior lumen containing 1 mM glucose and 1mM sodium chloride. If the vesicle is placed in pure water what will happen first?

A. Na + diffuses out.

B. cl - diffuses out.

C. H2O diffuses in.

D. Glucose diffuses out.

E. NaCl diffuses out.

The preferable statement will be - C.

C. H₂O diffuses in.

Explanation:

The synthetic vesicle is made up of pure phospholipids as our cells do. The cell contains 1 mM glucose and 1 mM sodium chloride at the intracellular lumen. This is the resemblance model of our cell. When the cell is placed into pure water, at very first, endosmosis will happen as the cell's concentration is too high. Pure water concentration is less than the cell's concentration. Low concentration fluid will go to the higher concentric substances. This is the reason water will diffuse into the cell quickly.
