Most of the starch stored in the cells of a potato is composed of molecules that originally entered these cells as

a.Enzymes
b.Simple sugars
c.Minerals
d.Amino acids

Respuesta :

Answer:

Correct option is B. (Simple sugar).

Explanation:

Starch is polysaccharide which is made up of many monomers know as monosaccharides which are known as sugar. All carbohydrates are made up of one or more sugar molecules.

Simple sugar are known as monosaccharides which is composed of single sugar molecule. Some examples of these sugars are fructose, glucose, and sucrose. When the body consumes these carbohydrate compounds they are converted to natural sugar molecules where they are used for energy.

Polysaccharides or complex carbohydrates are biomolecules consisting of many single sugar units. In complex carbohydrates, these subunits are held together by glycosidic bonds.

  • Most of the starch stored in the cells of a potato is composed of molecules that originally entered these cells as simple sugars (Option b).

  • Polysaccharides such as starch and glycogen are polymers (carbohydrates) composed of many simple sugar subunits, i.e., glucose molecules.

  • These glucose molecules are monosaccharides, which bind by glycosidic bonds to form different types of carbohydrates such as disaccharides (two monomers) or polysaccharides (many monomers).

  • Some examples of single sugar units include, among others, glucose, fructose and galactose.

In conclusion, most of the starch stored in the cells of a potato is composed of molecules that originally entered these cells as simple sugars (Option b).
