Bioluminescence - if it gives of visible light. However heat is also light and metabolism itself therefore gives off light, but you can not see it because it is infrared light.
Thousands of chemical reactions take place in an organism.
The reaction is exothermic.
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
It is an oxydation reaction.
The (general) name of proteins that makes chemical reactions inside the body work is 'enzyme'. Enzymes have a 'catalyst' function. There is one for each specific biological reaction.
Light emitted from living organism as a result of naturally occurring chemical reaction inside the organism.
Autotrophs
Metabolism.
Thousands of chemical reactions take place in an organism.
Almost all bio-chemical reactions taking place in the cells of the living organism are catalyzed by enzymes.For Example: The conversion of Glucose to Glucose-6-Phosphate (1st Reaction of Glycolysis) is catalyzed by the enzyme hexokinase or glucokinase.Glucose + ATP ---> Glucose-6-Phosphate + ADP
The reaction is exothermic.
a physical reaction you can see and a chemical is the molecules changing inside the object

Chemical Engineering is mainly based on Chemical Reaction Engineering. It is the things which happens inside the production reaction ( Which is what they do in production engineering but not in the chemical aspect )
Combustion.
A chemical reaction takes place inside hot air balloons whenever they are flying. Specifically, the propane tanks used to heat the air inside the balloon create a combustion reaction.
