Biomolecules and Their Functions

Which biomolecule is the main source of energy for cells?

• Nucleic acids

• Lipids

• Carbohydrates

• Proteins

What is the building block of proteins?

• Amino acids

• Fatty acids

• Nucleotides

• Glucose

Which biomolecule is responsible for storing genetic information?

• Lipids

• Carbohydrates

• Proteins

• Nucleic acids

Lipids are important because they:

• Provide short-term energy storage

• Form cell membranes

• Store genetic information

• Provide structural support

The primary role of carbohydrates in the body is to:

• Store energy long-term

• Provide quick energy

• Build muscle

• Store genetic information

Which of the following is an example of a protein?

• Glucose

• Enzyme

• DNA

• Fat

DNA and RNA are examples of:

• Proteins

• Carbohydrates

• Nucleic acids

• Lipids

What are lipids primarily made of?

• Amino acids

• Nucleotides

• Fatty acids

• Sugars

Nucleic acids like DNA are made up of building blocks called:

• Nucleotides

• Amino acids

• Fatty acids

• Monosaccharides

Proteins play a key role in:

• Storing genetic information

• Providing structural support and catalyzing reactions

• Long-term energy storage

• Forming the cell membrane
