Virola KMHS Biomolecules Quiz

Which of the following is represented in the image?

• Nucleotide
• Carbohydrate
• Lipid
• Protein

What elements do all biomolecules have in common?

• Carbon, Hydrogen, and Oxygen
• Carbon and Hydrogen
• Carbon, Hydrogen, Oxygen, and Nitrogen
• Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, and others

What biomolecule can NEVER be used for energy?

• Carbohydrates
• Lipids
• Proteins
• Nucleic acids

What is the best definition of the function of nucleic acids?

• They contain defense mechanisms against bacteria
• They contain the information that makes you and makes you different from every other living thing
• They are used as the structural components of the body (muscles and organs)
• They create the cell membrane

Which of the following statements is true? 

• The function of the biomolecule nucleic acid is carrying genetic code and the main source of energy for the body. 
• The function of the biomolecule carbohydrate is energy storage and make up the cell membrane. 
• The function of the biomolecule lipid is the main source of energy and structure and support. 
• The function of the biomolecule protein is structure or support and enzymes speed up the chemical reactions. 

The molecule in the diagram plays what role in the body?

• Releasing Energy
• Forming part of the sugar-phosphate backbone of DNA
• Storing Fat
• Controlling blood glucose levels

I am made up of nucleotides
I contain C, H, O, N, P
I am used to store genetic information
What am I? 

• Carbohydrate 
• Lipid
• Protein
• Nucleic Acid

All 4 biomolecules - 

• Contain C, H, O, N
• Contain C, H, O
• Are made up of Sulfur
• Are made up of Amino Acids

Both Carbohydrate & Lipids contain C, H, and O. How can we distinguish between these 2 biomolecules? 

• Carbohydrate have more oxygen
• In lipids, the # of carbon equals the number of oxygen
• In carbohydrate, the # of carbon equals the number of oxygen 

What is a key difference between carbohydrates and proteins?

• Proteins contain nitrogen; carbohydrates do not.
• Carbohydrates are biomolecules; proteins are not.
• Protein contains hydrogen and carbohydrate does not. 
• Proteins contain covalent bonds; carbohydrates do not.
