Biomolecules Practice

Biomolecules are the main groups of molecules that make up all living things. Which of the following is not a biomolecule?

• Protein

• Amino Acids

• Carbohydrates

• Nucleic Acids

When you have a fever, the high temperatures can denature (break down) proteins, one of the major biomolecules. When the proteins are denatured, their structures can change. How would this change in structure directly affect the proteins? Choose the best answer.

• The proteins will increase in strength.

• The proteins’ functions will change.

• The proteins will no longer work at all.

• The proteins will work better.

Carbohydrates are more easily metabolized than lipids. However, on a gram-for-gram basis, lipids provide cells with more -

• nitrogen

• proteins

• structure

• energy

Nucleic acids are one of the four major macromolecules. The main function of nucleic acids is to -

• aid in development, the immune system, and blood clotting.

• absorb energy from the Sun and transport it around the cell.

• carry genetic material that helps to create structures inside the cell

• act as enzymes, cell signals, and structural support for the cell.

Nucleic acids, proteins, and other large biological molecules are known as polymers because

• They all contain only ionic bonds.

• they contain many small, repeating subunits bonded together.

• They all have the capability of functioning as enzymes.

• They are the base units used in the formation of plastics.

True or false: the building blocks of biomolecules are called polymers

• True

• False

Like complex carbohydrates, proteins are biomolecules that serve many functions and can be chemically broken down and restructured. Both proteins and complex carbohydrates are which of the following?

• Polymers of small subunits

• Sequences of sugars

• Lipids of large molecules

• Nucleotides of DNA

A student wanted to make a comparison of sports to biomolecules. She said that in the Texans football team, the individual players are like the polymers while the entire team is the monomer. Make a claim about whether her statement was accurate, including evidence and reasoning.
