Answer:
All of the choices are correct.
Explanation:
- When a substance emits light which is not a result of heat, then such a spontaneous emission fo light is known as luminescence.
- Several chemical reactions or electrical energy can lead to the production of luminescence by organisms.
- The enzyme that is responsible for the production of bioluminescence by the organism is luciferase and it is capable of producing luminescence by catalyzing oxido-reductive processes.
- Luminescence is also produced in bacteria, and it is often controlled by the process of quorum sensing.
