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

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 Copyright ? 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Fig. 7-1 Concept 7.1: Cellular membranes are fluid mosaics of lipids and proteins ? Phospholipids are the most abundant lipid in the plasma membrane
