Question
In which ways is gluconeogenesis the reverse of glycolysis?
Multiple answers: You can select more than one option
A gluconeogenesis uses most glycolysis reactions in reverse mode. The direction of the reaction is determined by the concentration of reagents and products in the pathway.
B phosphoenolpyruvate and pyruvate interconversions directed by pyruvate carboxylase/PEP-carboxykinase AND pyruvate kinase are the first steps that commit the onset of gluconeogenesis.
C gluconeogenesis and glycolysis are independent pathways.
D fructose 16P and fructose 6P interconversions directed by fructose 1-6 bisphosphatase AND phosphofructokinase is the first step that determine the onset of glycolysis.
E gluconeogenesis produces pyruvate and glycolysis makes glucose
*Don't bother answering if you don't know the right answer*
Explanation / Answer
The correct answer is option B and D. Gluconeogenesis is the synthesis of glucose from non-carbohydrate precursors. The reciprocal regulation is also mediated by allosteric regulators of key enzymes, energy charge, fructose 2,6-biphosphate and hormones.
