Which motion of particles across a membrane requires energy?
A. from low concentration to high concentration
B. through dynamic equilibrium
Answer (2)
The movement of particles from low concentration to high concentration requires energy, known as active transport, while movement through dynamic equilibrium does not. Active transport uses ATP to move substances against their concentration gradient. Common examples include ion pumps and glucose transporters. ;
The motion of particles from low concentration to high concentration requires energy, which is known as active transport. This process involves moving substances against their concentration gradient and typically uses ATP for energy. In contrast, motion through dynamic equilibrium does not require energy, as the particles move at equal rates.
