POSSIBLE POINTS: 4 Fireflies emit light. The production of light by an organism is called bioluminescence. To generate visible light, cells in a firefly's tail produce
thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical
reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of
the following best describes how the luciferase enzyme speeds up the chemical reaction?
Luciferase increases the amount of time the light is visible.
Luciferase decreases the amount of energy required for the reaction to start.
Luciferase increases the number of sites on luciferin that must bind to oxygen.
Luciferase decreases the temperature of the environment inside the body of the firefly.

Luciferin is used, for example, in reporter gene assays to study gene regulation and function where expression of the luciferin-tagged reporter is a marker to indicate successful uptake of the gene of interest in recombinant DNA techniques. Luciferase is a heat-sensitive protein that is used in studies on protein denaturation, testing the protective capacities of heat shock proteins. Luciferase is an enzyme used for bioluminescence by various organisms in nature, most famously the firefly. The scientist produces a construct in which the regulatory region of a target gene is fused with the DNA coding sequence for luciferase
