The diagram below shows molecules flowing across a cell membrane. During diffusion, molecules are said to flow down their concentration gradient, flowing from an area of high concentration to an area of low concentration

Question; At what point in time (A,B,or C) has equilibrium been reached? Explain why you made that choice.

The diagram below shows molecules flowing across a cell membrane During diffusion molecules are said to flow down their concentration gradient flowing from an a class=

Respuesta :

my guess is c because both sides have 14 dots, which is equal.

At point C, it will reach at equilibrium i.e., no diffusion will happen.

What is diffusion?

  • "Diffusion is a process that happens as a result of random molecular mobility and ends up in a net movement of matter from a high-concentration region to a low-concentration zone."
  • "The concentration gradient is the difference in a substance's concentration between two regions."

What is equilibrium?

  • Equilibrium is the situation during which the concentrations of the diffusing substance within the two compartments are the identical or equal.

At point A, the extracellular space has high concentration of molecules. So, at B, it starts to flow from its higher concentration to its lower concentration (in intracellular space). At point C, the extracellular and intracellular space has equal concentration of molecules (in equilibrium) and no diffusion will occur at this point.

Hence, the correct answer is: Point C.
