Question

Is the "firefly making themselves glow" reaction endothermic or exothermic? Why?

Please help me. Will medal you! :-)

Answer 1

endothermic!

Answer 2

Endothermic, due to the fact that it is an internal reaction that is created by the organism exothermic are those creatures such as reptile and fish that require an outside stimulus such as the sun or heat vats.

oh i get what u were saying!!!! lol

Answer 22

did it work when i gave u the medal?

Answer 23

No, it is an exothermic reaction. You guys are mixing endotherms vs. exotherms with endothermic vs. exothermic. Endotherms are organisms that are able to regulate their internal environment over a range of external environments.

However, the question is asking only about the reaction that provides the "glow" in fireflies. This reaction is exergonic, meaning the reaction releases energy. In this case the reaction gives off energy in the form of light and heat, thus the exothermic (releases heat energy) reaction.

Does this help clarify it?
