2-10-11 BIOLOGY • People are show an interest in fireflies because these common insects give off light. Scientists have found that fireflies are not alone in this. Some kinds of bacteria, worms, squids, & jellyfish also give off light. This process, called bioluminescence, involves an exothermic reaction made possible by the enzyme luciferase. Scientists can use bacteria that contain luciferase to track the spread of infection in the human body.
