Question

One of the important reactions in the biochemical pathway glycolysis is the reaction of glucose-6-phosphate (G6P) to form fructose-6-phosphate (F6P):

a) Isomerization
b) Oxidation
c) Reduction
d) Dehydration

Answer 1

The conversion of glucose-6-phosphate into fructose-6-phosphate during glycolysis is an example of an isomerization reaction, facilitated by the enzyme phosphogluco-isomerase.

Step-by-step explanation:

The reaction of glucose-6-phosphate (G6P) to form fructose-6-phosphate (F6P) in glycolysis is an isomerization process. Isomerization is a reaction where a molecule is converted into one of its isomers, meaning a different arrangement of atoms but with the same atomic composition.

In this reaction, the enzyme phosphogluco-isomerase converts G6P into one of its isomers, F6P. This is an important step in glycolysis because it prepares the six-carbon sugar for the eventual split into two three-carbon molecules later in the pathway.
