Question

56:52 Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy? hypertonic transport active transport passive transport dynamic equilibrium

Answer 1

Answer:

The movement of particles from a high concentration area to a low concentration area through the plasma membrane without requiring energy is done by the process of passive transport.

Explanation:

Passive transport is a transmembrane transport mechanism that does not require energy and depends on a gradient of particle concentration.

The plasma membrane is a semi-permeable barrier to the passage of substances, which require transport through them by various transport mechanisms, including passive transport.

The different concentrations of particles on each side of the membrane create a gradient, which makes the movement of particles from the area of highest concentration to the area of lowest concentration, which in some circumstances is a passive transport mechanism, such as simple diffusion or facilitated diffusion.

The other options are not correct because:

• Hypertonic refers to a medium where there is a high concentration of particles.
• Active transport requires energy.
• Dynamic equilibrium refers to the continuous exchange of substances that occurs between the interior and exterior of the cells.
