Q. What are the few examples of the energetic function of organic molecules?
Ans.
Since they are complex molecules, organic molecules store large amount of energy, presenting many chemical bonds.
Glucose, for example, is the main energy source for the formation of ATP (adenosine triphosphate), a molecule that is necessary in several metabolic reactions. ATP is an organic molecule too and is itself the energy source for many biochemical reactions. Fat, like starch and glycogen that are polymers of glucose, proteins and some types of organic polymers, are energy reservoirs for the organism.
