It should be determined that, whether water is a weaker or stronger base than ammonia. Concept introduction: A base donates a pair of electrons to a proton. Basicity will decrease as an atom becomes more electronegative. For example: oxygen is more electronegative than nitrogen, therefore its electron are less likely to be donated to a proton. In the Bronsted – Lowery definition of acid and bases, An acid is a H + (proton) donor. A base is a proton acceptor. Conjugate acid formed when the proton is transferred to the base. In a conjugate base everything that remains of the acid molecule after a proton is lost. Conjugate acid = Base + H + Conjugate base = A cid + H +

Interpretation Introduction

Interpretation:

It should be determined that, whether water is a weaker or stronger base than ammonia.

Concept introduction:

A base donates a pair of electrons to a proton.

Basicity will decrease as an atom becomes more electronegative.

For example: oxygen is more electronegative than nitrogen, therefore its electron are less likely to be donated to a proton.

In the Bronsted – Lowery definition of acid and bases,

An acid is a H+ (proton) donor.

A base is a proton acceptor.

Conjugate acid formed when the proton is transferred to the base.

In a conjugate base everything that remains of the acid molecule after a proton is lost.

Conjugate acid = Base + H+Conjugate base = Acid + H+

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)?

Kranse et. al. measured the temperature dependence of conductance using membranescontaining the phospholipids glyceryl dipalmitate and glyceryl distearate. Describe themodifications in membrane content that you would employ to: (a) shift the temperature of the phase transition (b) make the ion conductance curve for valinomycin andnonactin more like that of gramicidin
