Question
Chapter 14, Problem 26CQ
Summary Introduction
To explain: The difference in free energy released from the hydrolysis of ATP and AMP.
Concept introduction: The equilibrium constant represents the relation between the products and reactants in a reaction at equilibrium. The concentrations of reactants and products are constant at the equilibrium. The spontaneity of a reaction depends on the decrease in free energy (ΔG) that indicates that free energy should be negative.

Suppose you wanted to make a buffer of exactly pH 7.00 using KH2PO4 and Na2HPO4. If the final solution was 0.18 M in KH2PO4, you would need 0.25 M Na2HPO4. Now assume you wish to make a buffer at the same pH, using the same substances, but want the total phosphate molarity ([HPO42−]+[H2PO−4]) to equal 0.20 M. What concentration of the Na2HPO4 would be required?

Their hypothesis was that phosphocholine joined with some cellular component to yield lecithin. In an earlier experiment, incubating 32 P-labeled phosphocholine at physiological temperature (37 °C) with broken cells from rat liver yielded labeled lecithin. This became their assay for the enzymes involved in lecithin synthesis.
