Is respiration a physical or chemical change?

can you explain the function of the electron transport change in cellular respiration, why is oxygen needed for the electron transport change?

  • Answer:

    When oxygen is present during cellular respiration, it will not use the process of fermentation. In the electron transport, the reduction of an NADH molecule produces 3 ATP molecules, and the reduction of an FADH2 molecule produces 2 ATP molecules.
