One reason people are fat is because they eat and eat and eat and don't exercise. Another reason is because some people have fast working calorie burning systems and some people have slow ones causing them to be fat.

It might be that those people that are not fat have high metabolism you eat as much as you want and not get fat.

Polysaccharides have more chemical bonds.

The energy in a glucose molecule is stored in the bonds between the atoms.

nucleid acids

Typically glycolysis. Glycolysis is a process by which sugars (specifically glucose) is broken down into ATP (energy). There are, however, many pathways to derive energy from differently moleculs (including lipids and carbohydrates).

Nucleic acids (DNA and RNA)

All organisms use the same genetic code.Living organisms are made of the same components as all other matter, organisms that inhabit the earth at any one time

they are all assembled from a nucleic acid code

Lipid (fat) molecules

They have the same bases in different orders
