What happens to a shape when reduction takes place

it gets smaller

Step-by-step explanation:

Reduction-oxidation chemistry in the environmental context blends biochemistry and geochemistry in ways that can make the transition from what you learned in general chemistry challenging. The driving force behind reduction-oxidation reactions in natural settings is microbial respiration, a complex series of electron-transfer reactions that ultimately couple cellular metabolism to the environment, consuming electron acceptors ranging from molecular oxygen to carbon dioxide in order to release the chemical energy stored in reduced carbon compounds.
