In biochemistry, the substrate is a molecule upon which an enzyme acts. What is its importance in Jellyfish? Bioluminescence occurs only when the enzyme luciferase catalyzes the oxidation of the luciferin molecule. Therefore, they require direct contact with their prey in order to feed which is effectively done through energetic propulsion in which pressure allows them to passively move in their environment.[7].
