Facilitated diffusion is a critical process that enables the transport of specific substances across the cell membrane with the assistance of specialized proteins. This passive transport mechanism relies on channel proteins and carrier proteins to move molecules like ions and glucose down their concentration gradient, ensuring efficient cellular function without energy expenditure. In this article, we explore the structure of the plasma membrane, the roles of transport proteins in facilitated diffusion, and their significance in maintaining cellular homeostasis and supporting physiological processes.
