(a)

Summary Introduction

To determine: The situation in which a protein has multiple subunits, each with a single ligand-binding site. Binding to one site decreases the binding affinity of other sites for the ligand.

Introduction:

The cooperative binding of oxygen to the hemoglobin was first described by Archibald Hill in 1910. The cooperative binding of oxygen to Hb is a form of allosteric binding in which the binding of one ligand (oxygen) affects the binding affinities of other remaining binding sites of the receptor molecule. The measure of the degree of cooperativity is denoted by nH, the Hill coefficient. If nH is equal to 1, the binding of ligand is not cooperative, if nH is greater than 1, the ligand binding indicates positive cooperativity, and if nH is less than 1 the ligand binding indicates the negative cooperativity. The plotting of hill equations on a plot of log Y versus log L is called a Hill plot.

Summary Introduction

(b)

To determine: The situation in which a protein is a single polypeptide with two ligand-binding site, each having a different affinity for the ligand.

Summary Introduction

(c)

To determine: The situation in which a protein is a single polypeptide with a single ligand-binding site. As purified, the protein preparation is heterogenous, containing some protein molecules that are partially denatured and thus have a lower binding affinity for the ligand.

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)?
