Question
Chapter 4, Problem 7P
Interpretation Introduction
Interpretation:
Why are GC and AT pairs made in a double helix?
Concept introduction:
A typlical structure of DNA has double stranded hydrogen bonding which forms a spiral configuration. Both of these strands are in opposite polarity. Purine never binds with another purine as they cannot fulfill the prerequisites of binding.

(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.arrow_forwardWhy did the authors worry about the temperature-dependent solubility of the carriers in thebilayer?
