Does Simple Diffusion Require Energy? Understanding Passive Transport
Discover why simple diffusion is a passive process that requires no energy as molecules move from high to low concentration until equilibrium is reached.

No, simple diffusion does not require energy. It is a passive process where molecules move from an area of high concentration to an area of lower concentration until equilibrium is reached. This movement is driven purely by the concentration gradient, requiring no external energy input.
FAQs & Answers
- What is simple diffusion? Simple diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is achieved.
- Does simple diffusion require energy? No, simple diffusion does not require any external energy as it relies solely on the concentration gradient.
- How does passive transport differ from active transport? Passive transport, like simple diffusion, does not require energy and moves molecules down their concentration gradient, whereas active transport requires energy to move molecules against their gradient.
