Transport Across the Cell Membranes
Transport across cell membranes is a fundamental process crucial for maintaining cellular homeostasis. Through a variety of mechanisms, cells regulate the passage of ions, molecules, and nutrients in and out of the cell. From simple diffusion to facilitated diffusion and active transport, these mechanisms ensure the proper functioning of cells by controlling the internal environment. Understanding the intricacies of transport across cell membranes is essential in fields ranging from biology to medicine, providing insights into cellular processes and potential therapeutic targets for various diseases.
