Both Active and Passive Mechanisms are Used to Move Materials

Question

Both active and passive mechanisms are used to move materials from the nephron back to the blood.

Accepted Answer

Both active and passive mechanisms are used to move materials such as sodium, glucose, and amino acids from the nephron back to the blood. Active transport requires energy, while passive transport does not. Examples of active transport include the sodium-potassium pump and the use of ATP to move molecules against their concentration gradient. Passive transport can occur through diffusion or facilitated diffusion, where molecules move along their concentration gradient. Both mechanisms work together to maintain the balance of ions and nutrients in the body.
