Biology (2.3) Questions

fatty acid

hydrocarbon chain often bonded to glycerol in a lipid.

lipid

non polar molecule composed of carbon, hydrogen, and oxygen; includes fats and oils

polymer

large, carbon-based molecule formed by monomers

carbohydrate

molecule composed of carbon, hydrogen, and oxygen; includes sugars and starches

amino acid

molecule that makes up proteins; composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur

protein

polymer composed of amino acids linked by peptide bonds; folds into a particular structure depending on bonds between amino acids

nucleic acid

polymer of nucleotides; the genetic material of organisms

Write your own analogy for the formation of a polymer from monomers.

string of holiday lights, beads on a necklace or bracelet, links in a chain...

What is the relationship between a polymer and monomer?

A polymer is a large molecule made up of smaller units called monomers, which are linked together.

How are both nucleic acids and proteins polymers?

Both are made of smaller units that are bonded together. Proteins are polymers of amino acids; nucleic acids are polymers of nucleotides.

What is the relationship between proteins and nucleic acids?

Proteins are polymers of amino acids that are assembled based on genetic information in nucleic acids.

monomer

a molecular subunit of a polymer

How are carbohydrates and lipids similar? How are they different?

Both: - made of carbon, hydrogen, & oxygen - broken down as a source of energy - have some structural functions Carbohydrates include starches & sugars Lipids include fats and oil
