The Effects of Temperature on Enzyme Activity and Biology ...

Biological and chemical reactions can happen very slowly and living organisms use enzymes to bump reaction rates up to a more favorable speed. Enzymes have multiple regions that can be activated by co-factors to turn them on and off. The co-factors are usually vitamins consumed through various food sources and open up the active site on the enzyme.
