If a chemical reaction catalyzed by an enzyme is being carried out, and there is a sudden, drastic decrease in temperature, what is most likely to happen next?

1.) Enzyme activity will decrease, and the reaction will proceed very slowly, or possibly not at all.2.) whales have cells that produce energy differently than humans.3.) It helps keep the organelles in place and directs their movement as needed.
