Glycolysis/Gluconeogenesis... several of the reactions of are easily reveresed and used in both pathways. Which reactions can be used in both pathways?

sapling learning this questionhas been custonice Elizabeth watson at virginia institute and State Unive Glycolysis is the the process by energy. Several of the reactions of are easily reversed and are used in both pathways. Others are not. ss by which energy is harvested from glucose by living things.

Explanation / Answer

The reactions that differ in bothe processes are;

1.Pyruvate to PEP conversion

2. Fructose 1,6 -Bisphosphate to Fructose -6-phosphate

3. Glucose 6 -phospahate to Glucose

in this question which are: J,C,A

Therefore the answer is : B,D,E,F,G,H,I
