Nitrogen Oxide

Explanation:

Volatile organic compounds (VOCs) are compounds that easily become vapors or gases.

Nitrogen Oxides are gases and compounds composed of nitrogen and oxygen. They are emitted from the burning of coal, oil, gas, cigarettes, stoves, wood burning, etc. They have a high photochemical reactivity, and when they do react with sunlight, they create smog, one of the most visible signs of poor air quality.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
