The wood in a match is made of cellulose, a polymer of glucose molecules. when you light the match heat and light are given off, indicating that a(n) reaction is occurring.

The given blank can be filled with exergonic reaction.  

An exergonic reaction demonstrates a reaction where energy is discharged. As the reactants lose energy, the Gibbs free energy is negative under constant pressure and temperature.  

An exergonic reaction, as mentioned in the given case and another process like cellular respiration refers to a reaction, which loses energy during the process of the reaction. An exergonic process is one in which there is a positive flow of energy taking place from the system to the surrounding.
