Answer
In aerobic respiration, the final product of the electron transport chain is water, which is formed when electrons combine with oxygen. This step is crucial as it helps to drive the electron transport chain and sustain cellular respiration.

Answer
Glucose is consumed during glycolysis and the Krebs cycle, but it is not a direct product of the electron transport chain and does not combine with it.

Answer
Pyruvate is produced during glycolysis and enters the Krebs cycle, but it does not combine with the products of the electron transport chain.
