Q. The conversion of glucose 6-phosphate in the second step of glycolysis is a(n) _______ reaction:

C) Isomerization

Explanation: In chemistry isomerization (also isomerisation) is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement

Glucose 6-phosphate is first isomerized to fructose 6-phosphate by phosphoglucose isomerase.

Here glucose 6-phosphate and fructose 6-phosphate has same number of molecules arranged in diferent way. Hence both are isomers. And this reaction is called as isomerisation.
