(c)

Interpretation Introduction

Interpretation:

Oxidizing and reducing agent in the given reaction should be determined.

Concept introduction:

Change in the oxidation number of atoms involved in the reaction is one of the special characteristic of reduction reaction.

The number of electrons an atom tends to give up or gain in a chemical reaction is called oxidation number.

Oxidation: Losing electrons, increasing oxidation number.

Reduction: Gaining electron, decreasing oxidation number.

Oxidizing agent is a substance that removes electrons from another reactant in a chemical reaction and so it is reduced by taking electron onto itself and the reactant is oxidized by having its electron taken away.

Reducing agent is the element or compound in a redox reaction that donate an electron to another species and so it is oxidized.

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 + ?
