(a)

Interpretation Introduction

Interpretation:

The energy diagram of a system with forward reaction having activation energy Eact=+25kcal/mol(+105kJ/mol) and with the reverse reaction having activation energy Eact=+35kcal/mol(+146kJ/mol) has to be sketched. The forward reaction is whether endergonic or exergonic has to be determined.

Concept Introduction:

  • Activation energy: It is defined as the minimum energy required by the reacting species in order to undergo chemical reaction.
  • Change in energy taking place in a reaction can be represented in a diagram called energy diagram.
  • Exergonic Reaction: In a chemical reaction if the free energy is released, it is known as exergonic reaction. The free energy is released due to the losing of energy from the reactant. The value of ΔG is negative and is spontaneous where the process takes place without the influence of any external source
  • Endergonic Reaction: In a chemical reaction if the free energy is absorbed, it is known as endergonic reaction. The free energy is absorbed by the reactant to form product. The value of ΔG is positive and is nonspontaneous where the process takes place by the influence of any external source

  • Free energy change (ΔG): Change in the free energy takes place while reactants convert to product. Free energy is the difference between the energy levels of reactant and product.

In 1956, E. P. Kennedy and S. B. Weiss published their study of membrane lipid phosphatidylcholine (lecithin) synthesis in rat liver. 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. Determine the optimal pH for this enzyme and characterize the enzyme activity at different pH values. -O-P-O-CH2-CH₁₂-N(CH3)3 Phosphocholine H₂C-O-C-R HC-O-C-R2 + + + Cell fraction + ? HC-O-P-O-CH₁₂-CH₂-N(CH), O Phosphatidylcholine The researchers then centrifuged the broken cell preparation to separate the membranes from the soluble proteins. They tested three preparations: whole extract, membranes, and soluble proteins. Table 1 summarizes the results. Table 1: Cell fraction requirement for incorporation of 32p-phosphocholine into…
Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?
