Did you present the steps of the procedure as a numbered list? Did you note any changes to the

original procedure?

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

not sure if this what   you'r looking for would be percent composition

trachea, alveoli, lung capillaries, arteries

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
