Which equation shows the cellular process that occurs more as a bird prepares to fly thousands of kilometers?

The correct answer would be C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

The given reaction refers to the reaction of cellular respiration which refers to the set of biochemical reactions by which organisms get energy from glucose.

The glucose is oxidized to produce adenosine triphosphate (ATP).

Carbon dioxide and water are produced as the byproducts.

Birds undergo aerobic respiration in order to get energy for long flight.
