Passive Transport: Essential Process For Efficient Substance Movement In Cell Membranes
Passive transport, a crucial process in cell membranes, involves the movement of substances across the membrane without energy expenditure. Substances move along concentration gradients, from high to low concentrations, facilitated by diffusion (direct membrane movement) and osmosis (water movement through semipermeable membranes). Unlike active transport, passive transport does not require carrier proteins or ATP, making…
