A student tested four unknown solutions of macromolecules with three reagents. She also tested the solubility of the solutions with water, a polar solvent, and hexane, a non-polar solvent. Her results are shown in the table below.

The activation energy required by the certain biochemical reaction to take place is shown by the given graph. Choose the correct graph, showing the effect of an enzyme on the same biochemical reaction.

Match the biological molecule listed under column I with their biological function listed under column II. Choose the answer which gives the correct combination of alphabets of the two columns.

The negative effect of excessive heat on enzyme function is that

Arrange the following compounds in descending order on the basis of number of carbon atoms present in them.
(A) Palmitic acid     (B) Serine    (C) Ribose   (D) Arachidoric acid     (E) Glucose

The given graph depicts the free energy change before, during and after a biochemical reaction. The effect of a catalytic enzyme can be described by

The way enzyme helps a substrate to be attacked by reagent effectively is :

The formation of phosphodiester bonds between two nucleotides can be considered as
