C'est quoi la DIFFUSION ? 🧬(SVT 1BAC SE)
Diffusion: A Fundamental Physical Phenomenon
Understanding Diffusion
- Diffusion is described as a physical phenomenon of passive transport, where solute particles (ions or atoms) move through a permeable membrane.
- The movement of these particles occurs from areas of high concentration to areas of low concentration, following the concentration gradient.
- This process is spontaneous and continues until the particles are evenly distributed, achieving an equilibrium state with equal concentrations on both sides of the membrane.
- Since diffusion does not require energy consumption or ATP, it is classified as a passive transport mechanism.
