In passive transport, solute movement continues even when the solute concentration is the same on both sides of the membrane.Group of answer choicesFalseTrue

Answer: True

In passive transport, solute movement, particularly through processes such as diffusion, occurs continuously even when the solute concentration reaches equilibrium on both sides of the membrane. This phenomenon happens because molecules are in constant motion, and while net movement may be zero at equilibrium (equal concentrations on both sides), individual molecules still move across the membrane in both directions.

This ongoing movement is characterized by random molecular motion and does not require energy, which is a key attribute of passive transport. The concept illustrates that while the concentration gradient drives the initial diffusion of solutes, once equilibrium is reached, the dynamic nature of molecular movement means solutes continue to cross the membrane without altering the overall concentration. Thus, the statement is correct: solute movement continues even at equilibrium in passive transport.
