100

This is the smallest unit of an element that retains its chemical properties.

What is an atom?

100

This functional group contains an -OH and often increases a molecule's ability to interact with water.

What is a hydroxyl group?
100

This is the simplest type of carbohydrate and serves as a monomer for larger carbohydrates.

What is a monosaccharide?

100

This type of lipid consists of one glycerol molecule bonded to three fatty acids.

What is a triglyceride?

100

These are the monomers that make up proteins.

What are amino acids?

200

This type of bond forms when atoms share electrons.

What is a covalent bond?

200

This functional group can donate H⁺ and is therefore typically acidic.

What is a carboxyl group?

200

This type of covalent bond joins two monosaccharides together.

What is a glycosidic bond?

200

These are the primary components of a triglyceride.

What are glycerol and three fatty acids?

200

These are the monomers that make up nucleic acids.

What are nucleotides?

300

This type of molecule has an uneven distribution of electrical charge because electrons are shared unequally.

What is a polar molecule?

300

This functional group contains a carbon double-bonded to oxygen.

What is a carbonyl group?

300

This is the primary short-term energy source provided by carbohydrates to cells.

What is glucose?

300

This type of fatty acid contains one or more carbon-carbon double bonds.

What is an unsaturated fatty acid?

300

This bond joins amino acids together to form a polypeptide.

What is a peptide bond?

400

This type of bonding is considered to be a transfer of electrons

What are ionic bonds?

400

This negatively charged functional group contains phosphorus bonded to oxygen and is commonly found in molecules such as ATP and phospholipids.

What is a phosphate group?

400

This type of carbohydrate is made up of two monosaccharides joined together.

What is a disaccharide?

400

This type of lipid contains a hydrophilic head and hydrophobic tails and is a major component of cell membranes.

What is a phospholipid?

400

This bond connects nucleotides within the sugar-phosphate backbone of DNA and RNA.

What is a phosphodiester bond?

500

These electrons are located in an atom's outermost energy level and are primarily responsible for its chemical behavior.

What are valence electrons?

500

This functional group can accept an H⁺ and is therefore commonly associated with basic properties.

What is an amino group?

500

This type of carbohydrate consists of many monosaccharides linked together and includes molecules such as starch and glycogen.

What is a polysaccharide?

500

This property allows phospholipids to interact with both water and nonpolar substances, causing them to form structures such as bilayers.

What is amphipathicity?

500

These three components make up a nucleotide.

What are a sugar, phosphate group, and nitrogenous base?
