Pleeeeeeees help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Which could be the catalyst in a chemical reaction?
reactants
product
enzyme
activated complex

Answer 1

A catalyst is something that is used to lower the activation energy of a reaction, that is later regenerated by the reaction (but the equilibrium isn't altered). In this case, an enzyme is an organic (protein) catalyst, so that's your answer.
