Gavin Morgan 10/9/2015 Chapter 5 2-Point Notes The fluid mosaic model shows proteins embedded in a fluid lipid bilayer: 1. The lipid layer that forms the foundation of a cell?s membranes is a bilayer formed of phospholipids. 2. Globular proteins are inserted into the lipid bilayer, with their nonpolar segments in contact with the nonpolar interior of the bilayer and their polar portions protruding out from the membrane surface. Cellular membranes consist of four component groups: 1. A eukaryotic cell contains many membranes. 2. Cell membranes are assembled from: Phospholipid bilayers, transmembrane proteins, interior protein networks, and cell-surface markers.

Membrane Structure and Function Chapter 7 Overview: Life at the Edge The plasma membrane is the boundary that separates the living cell from its surroundings The plasma membrane exhibits selective permeability, allowing some substances to cross it more easily than others ? 2011 Pearson Education, Inc. Figure 7.1 Concept 7.1: Cellular membranes are fluid mosaics of lipids and proteins Phospholipids are the most abundant lipid in the plasma membrane Phospholipids are amphipathic molecules, containing hydrophobic and hydrophilic regions The fluid mosaic model states that a membrane is a fluid structure with a ?mosaic? of various proteins embedded in it ? 2011 Pearson Education, Inc.

Which of the following statements is NOT true? a. Phospholipids can move laterally in a membrane but rarely move from the extracellular to the intracellular side. b. Plasma membranes are more like a fluid than a solid. c. In a plasma membrane, the hydrophobic portion is oriented to the inside of the membrane. d. Lipid molecules make the cell membrane relatively impermeable to water. e. Saturated phospholipids make a more fluid membrane.

Cell Membrane Fluid Mosaic Model: Cell membranes consist of a fluid formed by a phospholipid bilayer and a ?mosaic?, or patchwork, of proteins Phospholipid: Polar and hydrophilic head, nonpolar and hydrophobic fatty acid tail Cell membrane also called plasma membrane Outside the membrane there is interstitial fluid, which is a salty liquid Inside the membrane there is the cytosol, which is mostly water. The cytosol is also the water portion of the cytoplasm Phospholipid bilayer: Formed since the hydrophilic heads form hydrogen bonds with water, causing the heads to face the water on either side. Since the fatty acid tails are hydrophobic, they cluster together within the bilayer
