### Endgame 12

How do you tell if something is a catalyst? For example, in endgame 12, why is D not a catalyst?

You can determine if a molecule is a catalyst by looking at how it appears throughout the steps of a reaction. If the species appears first as a reactant which is consumed and then in a later step reappears as a product, it would be considered a catalyst.
