Carbohydrates are the macromolecule that performs both energy storage and structural functions in living organisms.Glucose is an example of a carbohydrate that stores chemical energy and cellulose is a carbohydrate that provides structural support in plant cell walls.
glucose
Lipids store more energy per gram than carbohydrates or proteins.
Carbohydrates would be the most useful biological macromolecule for running a marathon as they provide a quick source of energy to fuel the muscles during endurance activities. Consuming complex carbohydrates before the race can help store glycogen in the muscles for sustained energy, while simple carbohydrates during the race can provide immediate energy.
Polysaccharides
The macromolecule that stores energy in muscles is glycogen. Glycogen is a polysaccharide that serves as a readily available energy source for muscle cells during physical activity.

glucose
The organic macromolecule used for the long term energy storage in animals is triglyceride.
Nucleic Acids
Lipids store more energy per gram than carbohydrates or proteins.
That is the glucose. It is a monosaccharide
Protein
Starch
Most probably electrical energy.
