Lipid Metabolism Pathways
The citric acid cycle is considered to be the central metabolic pathway for all the following reasons, except:
a) It is involved in the metabolism of sugars and amino acids.
b) Many of its intermediates are starting points for synthesis of a variety of compounds.
c) All of these are reasons why the citric acid cycle is considered to be the central pathway.
d) It is involved in the metabolism of amino acids and lipids.
e) It links anaerobic metabolism to aerobic metabolism.
Seeing as A, B, D, and E are all correct, and C is irrelevant, i would go for C, but if I were you I’d also complain about the poor attempt at a trick question too.
