The proteins known as enzymes are vital to living things because they speed up chemical reactions up to a trillion times.
an enzyme
Living things use enzymes instead of a heat source of activation energy because they speed up chemical reactions as well as the metabolism in those living things.
Living things will grow, metabolize, reproduce, respond to stimuli and adapt to their environment. Non-living things may do one or more of these things (for example a crystal may grow) but will not do all five.
The living things have life while the non-living things do not have life. The living things locomote and respond to stimuli while the non-living things do not.
The function of enzymes in living things is to catalyze (instigate, speed up) chemical reactions.
