The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that: Are substrate level phosphorylations Are irreversible. Are regulated steps. Operate close to equilibrium. g

The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.

Explanation:

Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism.  Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.

Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.

Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".
