Answer:
The correct answer is option A.
Explanation:
Carbohydrates are one of the important biomolecule present on the earth. they are made up of carbon(C), hydrogen(H) and oxygen (O) in 2:1 ratio.
The carbohydrates play significant roles in organisms as:
1. Source of energy : undergo breakdown to provide energy.
2. Storage form: glycogen in animals and starch in plants.
3. Structural role: cellulose in plant cell wall provide the structural hardness and rigidity to the cell wall. Cellulose is a polysaccharide formed by the polymerization of D-glucose via f β-1,4 linkage in linear fashion.
Thus, option A is the correct answer.
The carbohydrate can be commonly used as cellulose which is the structural component in plant cell walls.
Further Explanation:
Carbohydrate, proteins and lipids are the major biomolecules present in all the living organism.
Proteins are made up of amino acid monomers joined by peptide linkage while lipids are made up of fatty acids joined by ester linkage. The carbohydrate is made up of monosaccharide monomer linked by glycosidic linkage.
There are many kinds of carbohydrates:
1. Monosaccharide: glucose and fructose
2. Disaccharide: sucrose and maltose
3. Polysaccharide: starch and cellulose
Carbohydrates plays various roles as they can serve as the immediate source of energy such as glucose or they can be used as storage energy such as starch and glycogen. They can also act as structural components.
Cellulose act as the structural component of the plant cell wall and it consists of glucose molecule as the monomeric unit.
Keratin is the protein molecule that provides support to hair and nail cell.
Enzyme is made up of proteins that catalysis the chemical reaction occurring in the living organisms.
Collagen is a protein molecules which is a major component of cartilage and tendons.
