Study Notes
Cell Membrane Transport Mechanisms
- Passive transport mechanisms do not require energy to move substances across the cell membrane.
- Facilitated diffusion is a specific type of passive transport mechanism.
- Active transport mechanisms move substances against their concentration gradient, requiring energy.
- Simple diffusion can occur through both the lipid and protein layers of the cell membrane.
Cell Membrane Permeability
- Cell membranes can be either permeable or semipermeable to substances, affecting the flow of molecules across the membrane.
