Macromolecules

Lemurs’ are animals native to only the island of Madagascar off the coast of Africa. They are in the Primate family that includes monkeys, apes, and humans. Their bodies are adapted to efficiently store energy for times when food is scarce.  This adaptation may help to explain how lemur ancestors survived the trip across the Mozambique Channel from mainland Africa to Madagascar.  Which of the following types of molecules are primarily used for long-term energy storage in the lemur?

• Lipid

• Protein

• Nucleic Acid

• Carbohydrates

An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide energy. Which two biomolecules must the supplement contain to provide these benefits?

• Lipids and nucleic acids

• Carbohydrates and lipids

• Proteins and carbohydrates

• Nucleic acids and carbohydrates

Based on the biological molecule below, what is the monomer of this molecule?

 

• Oleic acid, a fatty acid

• Leucine, an amino acid

• Glucose, a monosaccharide

• Cytosine, a nitrogenous base

Like complex carbohydrates, proteins are macromolecules that serve many functions and can be chemically broken down into smaller subunits. The following is a diagram of the product of protein synthesis. This protein is a polymer made up of molecules, labeled Z. What is the monomer labeled Z is most likely classified as?

• Lipids   

   

• Saccharides

• Nucleotides

• Amino Acid

Which of the following macromolecules is not matched correctly with its function?

• Carbohydrates = short term energy, component of cell wall

• Lipids = long term energy, component of cell membrane

• Proteins = provide energy needed for muscle growth and protein synthesis

• Nucleic acids = stores genetic information and involved in protein synthesis
