Question

Which of the following represents the correct order of events? a) Food → Krebs cycle → Glycolysis → Fermentation b) Food → Glycolysis → Krebs cycle → Electron transport chain c) Food → Fermentation → Electron transport chain d) Food → Photosynthesis → Krebs cycle e) Food → ATP synthesis → Glycolysis

Answer 1

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)).

Answer 2

The answer is B. Glycolysis is first the parvate then that goes into the keen cycle and finally to the electron transport chain
