Question

Quizplus · Accepted Answer

Bioluminescent microbes may have evolved due to aerobic metabolism, and they commonly have the enzyme luciferase, which catalyzes the reaction that produces light. They are also often beneficiaries of symbiotic relationships with larger hosts, receiving nutrients in exchange for their light-producing abilities.
