Transport Across Cell Membranes
infoWhy this? Selective membrane permeability allows cells to exchange materials while maintaining internal conditions. Understanding diffusion, osmosis, and active transport explains nutrient uptake, waste removal, and changes in cell volume.
scheduleWhy now? Knowledge of biological molecules and cell structure allows us to connect membrane composition with transport mechanisms. These principles are needed for digestion and absorption, gas exchange, mass transport, and later regulation of water potential.
