Asked by admin @ 28/10/2021 in Biology viewed by 287 People

Carbohydrates, such as glucose, are excellent sources of immediate energy for living organisms. More complex carbohydrates, such as glycogen and starch, can also be used for the long term storage of energy. However, carbohydrates play other vital roles, too. Which of the following describes another common use for carbohydrates?

A.Cellulose is used as a structural component in plant cell walls.
B.Collagen is a major component in cartilage and tendons.
C.Enzymes help speed up metabolic reactions.
D.Keratin provides support in hair, nails, feathers, hooves, and some animal shells

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.
