Chemicals that chemical reactions occur at
faster rates in living organisms are known as
(1) biotic resources
(2) simple sugars
(3) oxygen molecules
(4) organic catalysts

(4) organic catalysts

The job of catalysts in chemical reactions is to make the reaction go faster by lowering the amount of energy needed to activate the reaction. If less energy is needed for the reaction to occur, then the reaction can go faster because a large energy build-up is not needed.

That is true! many fish species traveled to the u.s. because of it.
