Final answer:
The correct sequence of cellular respiration stages is Glycolysis, Krebs cycle, and Electron transport chain, corresponding to option 1.
Step-by-step explanation:
The correct order of the three main stages of cellular respiration is: Glycolysis, Krebs cycle, and the Electron transport chain. Hence, the correct answer to the question is option 1) Glycolysis, Krebs cycle, Electron transport chain.
In the first stage, glycolysis occurs in the cytoplasm and involves the breakdown of glucose into pyruvate, with a net production of ATP.
The second stage, the Krebs cycle, takes place in the mitochondrial matrix and further processes pyruvate to produce energy carriers. The third and final stage is the electron transport chain, which occurs on the inner mitochondrial membrane, where energy from the carriers is used to synthesize a significant amount of ATP through oxidative phosphorylation.
