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?A) Luciferase increases the amount of time the light is visible. B) Luciferase decreases the amount of energy required for the reaction to start. C) Luciferase increases the number of sites on luciferin that must bind to oxygen. D) Luciferase decreases the temperature of the environment inside the body of the firefly.
