Cellular Transportation Josey Nelson Introduction Helps in maintaining homeostasis Two types: Passive Transportation No energy required Two main types High to low concentration Active Transportation Uses ATP for transportation Low to high concentration Diffusion The movement of particles from high concentration to low concentration Purpose: to reach equilibrium Osmosis is diffusion of water 3 major types Diffusion of ions Diffusion of molecules Osmosis (diffusion of water) Facilitated Diffusion Uses proteins to transport ions and molecules High to low concentration Requires Carrier Proteins No ATP (energy) Types of Solutions Hypotonic: a solution that contains higher water concentrations in solution

CHAPTER 7 MEMBRANE STUCTURE AND FUNCTION Membrane Structure Explain the meaning of the statement that phospholipids and most other membrane constituents are amphipathic molecules. It means that they have both a hydrophilic region and a hydrophobic region. Explain how the fluid mosaic model of a membrane is structured and the evidence that supports the model. The membrane is a fluid structure with a mosaic of various proteins embedded in or attached to a double layer of phospholipids. Using freeze-fracture to study cells under an electron microscope has shown a pattern that appears to agree with the fluid mosaic model. Describe the fluidity of the components of a cell membrane and explain how membrane fluidity is influenced by temperature and membrane composition.
