In the citric acid (Krebs) cycle, why is it described as a "cycle"?
A
Because the pathway regenerates oxaloacetate at the end, allowing acetyl-CoA to enter again and the sequence of reactions to repeat.
B
Because all reactions occur only in the cytosol and do not require mitochondrial enzymes.
C
Because each turn produces one molecule of glucose from units.
D
Because acetyl-CoA is regenerated at the end of the pathway to drive the next round.
