I think the correct answer from the choices listed above is option B. During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will stop moving across the membrane. This is because equilibrium has already been achieved and there is no more driving force which is the concentration gradient present.

During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will stop moving across the membrane.

Further Explanation:

Membrane transport, according to cell biology, indicates the group of mechanisms that aid in regulating the movement of the molecules such as ions via the biological membrane-like lipid bilayer. The movement of the passage via the membrane is known to be due to the selective permeability of the membrane.

The transport of molecules can either be active or passive transport. Passive transport refers to the movement of the ions or other molecules across the membrane without any input of the energy.

Passive transport can be of 3 types:

  • Simple diffusion
  • Facilitated diffusion
  • Osmosis

The process of diffusion is movement of a molecule or substance from higher concentration of an area to lower concentration area. Mostly diffusion occurs in gases and liquid. This process is very important for living things. The concentration gradient is referred as difference in the concentration of substance. The process of Diffusion cease when the concentration of molecule or substance is equal in both region.
