Answer:

The correct answer is C oxygen is directly used during aerobic respiration reactions .

Step-by-step explanation:

Cellular respiration deals with the breakdown of sugar molecule basically glucose in presence of oxygen(in case of aerobic respiration) or in absence of oxygen (anaerobic respiration) to generate breakdown products such as ATP.

During aerobic respiration reactions oxygen is directly used.The oxygen reacts with glucose in 3 important step a glycolysis b TCA cycle and c oxidative phosphorylation to generate CO2,H2O and ATP molecules.
