Cell membranes and transport
Cell membranes and transport — Cambridge International AS & A Level Biology (9700, AS Level, Topic 4).
Fluid Mosaic Membranes and Cell SignallingSign up
know the structure and properties of cell membranes · understand how models such as the fluid mosaic model are interpretations of data on membrane structure and properties · CORE PRACTICAL 3: investigate membrane properties including the effects of alcohol and temperature on membrane permeability · understand osmosis in terms of free water movement through a partially permeable membrane down a water potential gradient · understand passive transport (diffusion, facilitated diffusion), active transport (ATP-driven, including endocytosis and exocytosis), and the roles of carrier and channel proteins
