Chapter 9, Problem 5P

Answers to all problems are at the end of this book. Detailed solutions are available in the Student Solutions Manual, Study Guide, and Problems Book.

Understanding Diffusion of Proteins in Membranes Protein lateral motion is much slower than that of lipids because proteins are larger than lipids. Also, some membrane proteins can diffuse freely through the membrane, whereas others art bound or anchored to other protein structures, in the membrane. The diffusion constant for the membrane protein fibronectin is approximately 0.7 X 10-12 cm/sec, whereas that for rhodopsin is about 3 X10-9 cm/sec.

  1. Calculate the distance traversed by each of these proteins in 10 msec.
  2. What could you surmise about the interactions of these proteins with other membrane components?

Do schwann cells produce or act as myelin in the peripheral nervous system? I know that they encase and wrap around axons, but where does the myelin come into play?
The enzyme lactate dehydrogenase (LDH) catalyzes the conversion of pyruvate to lactatein skeletal muscle cells using NAD/NADH during anaerobic “balanced” fermentation.Answer the following questions about this reaction. (a) Write out the two reductive half reactions and indicate the E ̊' for each half reaction. Write out the full balanced reaction for the pyruvate to lactate rxn and indicate the ∆E ̊' for the reaction. (b) What is the free energy change under standard state conditions for thisreaction? Which direction is spontaneous?(c) Assume that in skeletal muscle cells the ratio of [NAD+] to [NADH] is 100, and that the[pyruvate] = 0.40 mM and [lactate] = 4.0 mM. What is the free energy change (∆G')for the conversion of pyruvate to lactate? Indicate the direction in which the reactionis spontaneous under these cellular conditions.
Why did the authors worry about the temperature-dependent solubility of the carriers in thebilayer? How did the authors determine whether the effect of freezing the lipid bilayer wasto decrease the solubility of the carriers (nonactin and valinomycin) or whether the effectwas to impair their ability to diffuse through the membrane (decrease their mobility)?
