Which of the following determines the diffusion of water from one cell to another?

Options

  1. ADiffusion pressure deficit
  2. BHydrostatic pressure
  3. COsmotic pressure
  4. DWall pressure

Correct answer

A. Diffusion pressure deficit

Step-by-step solution

The diffusion of water from one cell to another is a passive process that doesn't require any ATP.DPD is a diffusion pressure deficit and it was described as suction pressure by Renner in 1915. The DPD is the amount by which the diffusion pressure of water solvent in a solution is lower than that of pure solvent or water and they oppose the diffusion. Water movement occurs from lower DPD to higher DPD.
