The citric acid cycle - anabolic and catabolic

Question

The citric acid cycle is the only metabolic pathway that can be used

both as an anabolic and as a catabolic pathway.

TRUE / FALSE?

Answer 1

True.

The citric acid cycle can act in synthesis, as well as in breakdown

some of the organic acids, which are intermediates in the citric acid cycle, are the precursors for the synthesis of other molecules

for example, pyruvate, oxaloacetate, and alpha-ketoglutarate can be aminated (have an amino group added) to form the amino acids alanine, aspartate, and glutamate

since the citric acid does both synthesis (anabolic) and breakdown (catabolic) activities, it is called an amphibolic pathway.

Answer 2

TRUE

Answer 3

False....the glycolytic pathway participates in degradation and synthesis of glucose. ( glycolysis and gluconeogenesis )
