Question

Which of the following classes of biological molecules consist of both small molecules and macromolecular polymers?A) lipids

B) carbohydrates
C) proteins
D) nucleic acids
E) lipids, carbohydrates, proteins, and nucleic acids all consist of only macromolecular polymers

Answer 1

(Correct option is B) Carbohydrates.

Step-by-step explanation:

Biological molecules are known as the molecules which are found in the organisms, and play some important roles like development, cell division, and morphogenesis. They are necessary for the life.

Carbohydrates are known as the classes of biological molecules which consist of small molecules, and macromolecular polymers both. Carbohydrate are divided into three subtypes of essential macromolecules:

1) Monosaccharides: Fructose, galactose, and glucose are isomers of monosaccharide.

2) Disaccharides: Sucrose is the isomer of disaccharide.

3) Polysaccharides: Starch, cellulose, and glycogen are example of polysaccharide.

Glucose, and sucrose are known as the small molecules of carbohydrates, and other molecules of carbohydrate such as polysaccharides are known as macromolecular polymers.
