Answer:
The correct answer is b) Food → Glycolysis → Krebs cycle → Electron transport chain.
Explanation:
When food enters the organism it goes through a lot of processes to become the beginning of glycolysis which produces pyruvate, which turns into acetyl CoA, which at the same time is the beginning material of Krebs cycle. The products of this cycle provide energy for the electron transport chain (NAD(H) and FAD(H)).
