which motion of particles across a membrane requires energy?\nfrom high concentration to low concentration\nfrom low concentration to high concentration\nwith no concentration gradient\nthrough dynamic equilibrium

which motion of particles across a membrane requires energy?\nfrom high concentration to low concentration\nfrom low concentration to high concentration\nwith no concentration gradient\nthrough dynamic equilibrium

Answer

Answer:

B. from low concentration to high concentration

Brief Explanation:

Particles moving from low to high concentration go against the concentration - gradient and require energy (active transport). Movement from high to low concentration is passive and doesn't need energy. Movement with no concentration gradient and through dynamic equilibrium also don't require energy input for net movement.
