Nutrients and Biomolecules

Which biomolecule contains pastas and breads?

• Lipid

• Protein

• Nucleic Acid

• Carbohydrate

Answer explanation

Carbohydrates are the primary biomolecules found in pastas and breads, as they are rich in starches and sugars, which provide energy. Lipids, proteins, and nucleic acids do not primarily constitute these food items.

Which biomolecule is DNA made of?

• Carbohydrate

• Lipids

• Protein

• Nucleic Acid

Answer explanation

Nucleic acids are the biomolecules that include both DNA and RNA. They are essential for storing and transmitting genetic information, making them the correct choice for this question.

Which biomolecule helps form muscles?

• Nucleic Acid

• Carbohydrate

• Protein

• Lipids

Answer explanation

Proteins are essential biomolecules that play a crucial role in muscle formation and repair. They are made up of amino acids, which are the building blocks of muscle tissue, making protein the correct answer.

Which biomolecule is responsible for insulation and energy storage?

• Protein

• Nucleic Acid

• Lipid

• Carbohydrate

Answer explanation

Lipids are the biomolecules primarily responsible for insulation and energy storage in living organisms. They store energy in the form of fats and provide thermal insulation, making them the correct choice.

Which biomolecule produces sugars and starches?

• Lipids

• Proteins

• Carbohydrates

• Nucleic Acid

Answer explanation

Carbohydrates are the biomolecules that produce sugars and starches, serving as a primary energy source for living organisms. They include simple sugars like glucose and complex forms like starch.

What is a fat molecule that stores energy?

• lipid

• protein

• carbohydrate

Answer explanation

A lipid is a type of fat molecule that serves as a major energy storage form in the body. Unlike proteins and carbohydrates, lipids are specifically designed to store energy efficiently.

What is a type of nucleic acid that is found in ALL cells?

• nucleotides

• amino acids

• DNA

Answer explanation

DNA is a type of nucleic acid that carries genetic information and is found in all living cells. It is essential for the storage and transmission of genetic material, making it the correct answer.
