| oxygen | a colorless, odorless, gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature |
| carbon dioxide | a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air |
| glucose | a sugar, C6H12O6, having several optically different forms, the common dextrorotatory form (dextroglucose, or -glucose) occurring in many fruits, animal tissues and fluids, etc., and having a sweetness about one half that of ordinary sugar. |
