This is an example of a substance made of lipids.

What are waxes, fats, and oils?

100

This is a function of glucose in living things.

What is to provide energy?

100

This monomer of nucleic acids is made of a base, a sugar, and a phosphate group.

What is a nucleotide?

100

What type of reaction forms a peptide bond between two amino acids?

What is condensation?

100

The level of structure forms due to the interactions between R groups.

What is a tertiary structure?

200

This type of lipid has a long hydrocarbon tail, a carboxyl group head, and no double bonds in the hydrocarbon tail.

What is a saturated fatty acid?

200

Alpha and beta glucose are examples of these.

What are isomers?

200

This is the base that is present in RNA but absent in DNA.

What is uracil?

200

All amino acids have a central carbon that is bonded to hydrogen, and R group, a carboxyl, and this functional group.

What is amine?

200

The sequence of amino acids in a protein is this level of structure.

What is primary structure?

300

This type of reaction joins the subunits to make a triglyceride.

What is condensation?

300
Glycogen, amylose, and amylopectin are all made from this monomer.

What is glucose?

300

These two molecules make up the backbone of DNA.

What are deoxyribose sugar and phosphate?

300

These elements are bonded together in the main polypeptide chain in a peptide bond.

What are carbon and nitrogen?

300

This level of structure refers to the interactions between separate polypeptide strands to make a larger protein.

What is quaternary structure?

400

This type of lipid is the main molecule found in the lipid bilayer of cells.

What is a phospholipid?

400

This polysaccharide has a linear structure without coils and makes up plant cell walls.

What is cellulose?

400

This monomer of a nucleic acid is made of a base and a sugar.

What is a nucleoside?

400

These amino acids cannot be made by the body.

What are essential amino acids?

400
This type of secondary structure forms between parallel parts of a protein.

What is a beta-pleated sheet?

500

These are the subunits of a phospholipid.

What are phosphate, glycerol, and two fatty acids?

500

This polysaccharide is unbranched but has a coiled structure.

What is amylose?

500

These two scientists discovered the structure of DNA by making models.

Who are Watson and Crick?

500

This part of amino acids is the main determinant of how a protein folds into its final structure.

What are R groups?

500

Hydrogen bonds between the backbones of every fourth amino acid in a polypeptide chain produce this structure.

What is an alpha helix?
