Cofactors MOLECULAR BIOLOGY AND MOLECULAR GENETICS are molecules required by an enzyme (in this patient luciferase) 72 CREATION OF MICROBIOLOGY AND IMMUNOLOGY Bioremediation to carry out its catalytic party. Conventional cofactors required is the firefly, which can oftentimes be seen luminous during the keen for bioluminescent reactions are calcium and ATP, a molecule summer months. In some instances organisms utilize biolumines- old to store and make available puissance that is found in all organisms. The German scientist Emil du Bois-Reymond anchorage a mass of bioluminescent organisms including species obtained two different extracts from bioluminescent clams and of bacteria, dinoflagellates, jellyfish, coral, shrimp, and fish.
