Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that oxygen is the final electron acceptor in cellular respiration?

Yes. Multiple peer-reviewed and reference sources state that oxygen serves as the final electron acceptor in aerobic cellular respiration, including in mitochondria. A few sources note that under anaerobic conditions other compounds can substitute as the final acceptor.
