Understanding Diffusion in Biology
Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. This process plays a crucial role in various biological systems, allowing substances to move across cell membranes, facilitating essential functions such as nutrient uptake and waste removal.
Key Characteristics of Diffusion
1. Passive Process: Diffusion does not require energy input from the cell. Instead, it relies on the natural kinetic energy of molecules.
2. Concentration Gradient: Molecules move down their concentration gradient, which is the difference in concentration between two areas.
3. Equilibrium: The ultimate goal of diffusion is to reach equilibrium, where the concentration of molecules is equal in both areas.
4. Factors Affecting Diffusion:
- Temperature: Higher temperatures increase molecular movement, accelerating diffusion.
- Molecule Size: Smaller molecules diffuse more quickly than larger ones.
- Surface Area: Greater surface area allows for more molecules to diffuse at once.
