glycolysis and gluconeogenesis are "reciprocally regulated." Which of the following is TRUE about this reciprocal regulation of the two pathways?
A. AMP stimulates glycolysis and inhibits gluconeogenesis.
B. Fructose-2,6-bisphosphate inhibits gluconeogenesis and stimulates glycolysis.
C. Citrate stimulates gluconeogenesis and inhibits glycolysis.
D. Reciprocal regulation means that if both pathways can in principle operate in the same cells one pathway or the other predominates under a given set of physiological conditions.
E. All of the above are true statements.
