Textbook Question
Chapter 6, Problem 2IQ
- a. Describe the molecular structure of the plasma membrane.
- b. If a spherical eukaryotic cell has a linear dimension that is 10 times that of a spherical bacterial cell, how much more surface area, proportionally, would the eukaryotic cell have? Proportionally, how much more volume would it have?
- c. What size, shapes, and surface adaptations help provide a sufficiently high ratio of surface area to volume to accommodate the exchange of materials across the plasma membrane?

B.A protein that peripherally associates with the membrane via ionic interactions another protein embedded in the membrane.
C.A protein that is soluble in the cytoplasm.
D.A protein that peripherally associates with the membrane via ionic interactions between polar charged amino acids and the polar head groups of the phospholipids in the membrane.
