Quizplus · Accepted Answer

The correct sequence of stages in cellular respiration is glycolysis, preparatory stage, citric acid cycle, and electron transport chain. This is because during glycolysis, glucose is broken down into two molecules of pyruvate. The preparatory stage then converts each pyruvate molecule into acetyl-CoA, which enters the citric acid cycle. The citric acid cycle produces ATP, NADH, and FADH2, which then enter the electron transport chain to produce even more ATP.
