Answer:
The correct order of these elements from least to most complex is atom → molecule → carbohydrates → monosaccharide → disaccharide → polysaccharides.
Explanation:
Carbohydrates are organic molecules formed by carbon, hydrogen and oxygen, whose complexity is received in the amount of monomers they possess.
According to their level of organization, carbohydrates are constituted by:
- Atomic level: atoms of carbon, hydrogen and oxygen.
- Molecular level: these are the carbohydrate molecules that can be formed, from the simplest to the most complex:
- Monosaccharides: or simple sugars, such as glucose.
- Disaccharides: are formed by two monomers. An example of this is sucrose, formed by glucose and fructose.
- Polysaccharides: formed by chains of more than 2 carbohydrates, such as starch.
The term carbohydrate groups all possible forms of these molecules, from the simplest to the most organized molecular.
