Campbell's Biology, 9e (Reece et al.) Chapter 7 Membrane Structure and Function Membranes and membrane transport are fundamental to cellular life. The concepts in this chapter require integration of concepts from previous chapters: the nature of water and hydrophobic versus hydrophilic molecules, the properties of lipid molecules and their role in regulating membrane fluidity, and the roles of proteins and carbohydrates in membrane function. The concepts of ion transport and electrochemical gradients across membranes are important foundations for the following chapters on energy metabolism. Finally, the bulk transport phenomena have important clinical significance in the immune system, during invasion by pathogens, and in cell signaling. Multiple-Choice Questions

Beaks of Finches Why do offspring of better-adapted individuals inherit many of their parents? favorable variations? Beaks of Finches Why do offspring of better-adapted individuals inherit many of their parents? favorable variations? Favorable variations allow parents to survive and then reproduce more. Their offspring then may possess those variations. Beaks of Finches What are the parts of Darwin?s theory of Natural Selection?

Study tips for Quiz 3 Fluid mosaic membrane model Selective permeability: control what goes in and out of cell Compartmentalization: different processes can be separate Phospholipids-main component of membranes (50% by weight) Structure: hydrophilic heads faces out (water loving) polar surface Hydrophobic tails face in (weather fearing) non-polar region Interior 1972 singer and Garth Fluid- lipids and proteins can move relative to each other within membrane The typical membrane structure consists of a phospholipid bilayer with a number of proteins scattered throughout, along with some carbohydrates (glycoproteins), glycolipids and sterols, similar to the way in which one does a mosaic tile, hence the name. molecules involved in membrane transport Pg 107 fig 5.12
