PPT-Chapter 7: Membranes

Roles of Biological Membranes The Lipid Bilayer and the Fluid Mosaic Model Transport and Transfer Across Cell Membranes Specialized contacts junctions between cells What are the major roles of biological membranes. Conventional Ultrafiltration membranes are composed ofsome type of polymer material with pores ranging from alittle less than 0.01 m to 0.1 m. These membranes areused for many different separations i Bell task: Transport across membranes . Transport . Concentration gradient . Energy (ATP). Simple diffusion . Down (high to low) .
