The Lipid Barrier of the Cell Membrane‚ and Cell Membrane Transport Proteins The structure of the membrane covering the outside of every cell of the body is discussed in Chapter 2 and illustrated in Figures 2–3 and 4–2.This membrane consists almost entirely of a lipid bilayer‚ but it also contains large numbers of protein molecules in the lipid‚ many of which penetrate all the way through the membrane‚ as shown in Figure 4–2. The lipid bilayer is not miscible with either the extracellular

Review Questions Exam 2 Although I try to cover all materials thoroughly in these questions‚ anything covered in lecture may appear on the exam. Membrane Transport 1. Describe the cell permeability and membrane transport. What can enter/exit the cell on its own? What requires assistance? Why? 2. Describe membrane potential. What is it? How is it established? How does it influence the transport of charged molecules? What are the components of the electrochemical gradient?
