Irreversible steps in gluconeogenesis
WebExplain why the irreversible steps of glycolysis make calling gluconeogenesis “reverse glycolysis” invalid. Explain why glucose is considered a main source of cellular energy … WebSelect every irreversible reaction step The path of carbon through the glycolytic pathway is shown in the figure. Some of these steps are reversible and catalyzed by the same enzyme acting in either direction, glycolysis or gluconeogenesis. Note that many of these steps are reversible and should be shown with equilibrium arrows.
