Conversion of glucose 6-phosphate into fructose 6-phosphate is done by:
Correct answer: B. Isomerases
- A. Transferases
- B. Isomerases
- C. Oxidoreductases
- D. Hydrolases
Explanation
The conversion of glucose 6-phosphate to fructose 6-phosphate is a glycolytic pathway reaction catalyzed by the enzyme phosphohexose isomerase. This reaction involves the rearrangement of atoms within the molecule to form an isomer; hence, it is classified under Isomerases. Transferases would be incorrect as they transfer functional groups, not convert isomers. Oxidoreductases facilitate redox reactions, which do not occur in this process. Hydrolases break bonds using water, which is not involved in this isomerization.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
