Reduction Reaction

A chemical reaction that involves the gain of electrons or the decrease in oxidation state by a molecule, atom, or ion.

Carbon Dioxide

Produced during the burning of carbon and organic matter as well as through the respiration process, this odorless, colorless gas is a natural part of the atmosphere and essential for photosynthesis in plants.

NAD+
