Nutrient Transport Across Bacterial Membranes

This animation explores how bacteria move nutrients across their cell membranes, beginning with an overview of the membrane's structure and selective permeability. It then visually contrasts passive diffusion, facilitated diffusion, active transport, and group translocation (the phosphotransferase system), showing energy requirements, carrier proteins, and concentration gradients for each. A concluding summary ties the mechanisms together. Designed for fourth-year biology students studying microbial physiology and membrane transport systems.
