Cell Membrane Transport Mechanisms Study Guide
This guide covers the fundamental principles of how substances move across cell membranes. It differentiates between passive transport, which includes diffusion and facilitated diffusion driven by concentration gradients, and active transport, which requires cellular energy (ATP) to move substances against their gradients. The structure of the cell membrane, particularly the lipid bilayer and embedded transport proteins, is also explained as the basis for these transport processes. Understanding

Membrane Transport and Molecular Biology Fundamentals
Mechanisms of Passive Membrane Transport
Substances move through the phospholipid bilayer or protein channels from high concentration to low concentration without energy input.
- Concentration gradient
- Diffusion of lipid-soluble substance
- Passive transport of water-soluble substance
- Channel proteins
