Question

In the organisms which show bioluminescence, the chemical energy of cell is converted into

• A. Light energy
• B. Thermal energy
• C. Mechanical energy
• D. Heat

Answer 1

The correct option is A Light energy

• Bioluminescence is the process of production and emission of light from an organism.
• In this, the chemical energy is converted into radiant energy or light energy and is virtually 100 percent efficient; i.e., very little heat is given off in the process. For that reason, the emission is called cold light or luminescence.
• This is one adaptation for protection, as ninety percent of deep-sea marine life is estimated to produce bioluminescence in one form or another.
  
• It is generated by an enzyme-catalyzed chemoluminescence reaction, wherein the pigment luciferin is oxidized by the enzyme luciferase.

So, the correct answer is option A.
