When too much acetyl CoA accumulates because glucose is short, what does the body generate?
AExtra glycogen stores
BKetone body fuels
CMore pyruvate units
DNew pancreatic cells
Answer & Solution
Correct answer: B. Ketone body fuels
1. Acetyl CoA normally enters the Krebs cycle to be oxidised.
2. When too much accumulates, it is diverted to create ketone bodies instead.
3. Those ketone bodies can then serve as a fuel source when glucose levels are too low.
