A researcher cultures two samples of the same type of human muscle cells. Both samples are provided with the same amount of glucose and kept at 37°C. Culture A is maintained in an oxygen-rich environment, while Culture B is kept in an oxygen-free environment. After one hour, the ATP content of each culture is measured. Culture A contains significantly more ATP than Culture B.
Explain the cellular processes that lead to the much greater ATP yield from glucose in Culture A compared with Culture B. In your answer, refer to the stages of respiration and where they occur.
