What happens if a cell is at equilibrium with its surroundings?

Question

Group of answer choices

molecules continue to move equally into and out of the cell

more molecules move out of the cell than into the cell

molecules completely stop moving into or out of the cell

more molecules move into the cell than out of the cell

Answer 1

When a cell is at equilibrium with its surroundings, the correct choice is:

molecules continue to move equally into and out of the cell.

At equilibrium, the rates of movement of molecules into and out of the cell are equal, which means that there is no net movement of molecules, but they continue to move freely in both directions.
