transport across cell membrane pdf
Cell membrane transport is essential for cellular function, enabling the movement of molecules across the plasma membrane via passive and active mechanisms, maintaining homeostasis and metabolic processes. 1.1 Importance of Transport Across Cell Membranes Transport across cell membranes is vital for maintaining cellular homeostasis, enabling nutrient uptake, waste removal, and ion balance. It supports metabolic processes, signaling, and overall cellular function, ensuring proper interaction with the environment and sustaining life. 1.2 Brief Overview of Cell Membrane S
