What is the correct sequence for aerobic metabolic breakdown of glucose?

Question

is it

1 glycolysis 2 prep reaction 3citric acid cycle 4 ElectronTransSysytem

or

1 prep reaction, 2 glycolysis, 3 ETS, 4 citric acid cycle

or

1 ETS, 2 citric acid cycle, 3 prep reaction, 4 glycolysis

or none of them?

Answer 1

It's number 1. The electron transport chain accepts the final electrons to become water. Prep reaction "preps" of comes before the citric acid cycle.
