A reactant stops being itself the moment it becomes a product, and the evidence shows up as heat, a color change, or a cloudy precipitate settling out of a clear solution. Some reactions release energy as they go; an endothermic one pulls heat from its surroundings instead, which is why a cold pack works. A catalyst speeds up either kind without being used up itself.
