Fluid mosaic model Study guides, Class notes & Summaries

transport proteins - are responsible for controlling passage across the membrane fluid mosaic model - The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails - nonpolar, hydrophobic fatty acid heads - hydrophilic, polar periphial proteins - bound to the surface of the membrane integral proteins - penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How do cells recognize each other? - by binding to molec...

Test Bank Chapter 1. Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNAwith histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within itsnucleus; thus, the nucleus should be observed. A single circular c...

Chapter 5: Membrane Structure and Function AP Biology Fluid Mosaic Model Video The Basics ● The structure of cell membranes results in selective permeability ● Cell membranes separate the internal environment of the cell from the external environment. ● Selective permeability is a direct consequence of membrane structure as described in the fluid mosaic model. Fluid Mosaic Model 1. Singer and Nicolson (1972) introduced this model 2. Embedded proteins are scattered throu...
