Properties of Biological Molecules
100

Nonpolar covalent bonds 

What is a pair of electrons shared equally by 2 atoms?

100

What is a polar covalent molecule composed of? 

What is 2 Hydrogen and 1 oxygen molecule?  

100

Name four categories of organic molecules which form the basis of all living things.

What is the four categories of living things are carbohydrates, lipids, proteins, and nucleic acids? 

100

What is the difference between polymers and monomers? 

What is polymers are large molecules that are made up of many similar molecular building blocks, on the other hand, monomers are the building blocks. 

100

Monosaccharides 

What is carbohydrate monomers?

200

Pair of electrons shared unequally by 2 atoms

What is Polar covalent bonds?

200

Polarity 

What is an uneven distribution of charge throughout a molecule? 

200

Compositional elements of nucleic acid 

What is C, H, O, N, P? 

200

What is the monomer of carbohydrates? 

What are saccarides? 

200

Polysaccharides 

What is complex carbs (polymers)?

300

Most common weak bond

What is a Hydrogen bond? 

300

What is the difference between cohesion and adhesion? 

What is cohesion is water molecules that are attracted to one another through hydrogen bonding, while adhesion is water molecules allured to other polar molecules through hydrogen bonding? 

 

300

Compositional elements of proteins 

What is C, H, O, N (also S in some R groups)? 

300

Hydrolysis reactions

What is the reverse of dehydration reactions? 

300

What are the bonds between monosaccharides called? 

What is glycosidic bonds? 

400

Hydrogen bonding.

What is an attraction between a partially positive H in one H2O molecule to a partially negative O in another H2O? 

400

Universal solvent

What is water as it dissolves ionic and polar covalent solutes?

400

What are organic molecules composed of?


Carbon with attached Hydrogens.  

400

What is the transformation of monomers to polymers? 

What is polymerization? 

400

Why don't lipids dissolve in water? 

What is because all lipids are nonpolar?

Hydrophobic 

500

Occurs wherever
an -OH exists in a larger
molecule

What is a molecular attraction? 

500

How are the rungs of the ladder of DNA kept together?

What is they are kept together by hydrogen bonds between the nitrogenous bases? 

500

How are the building blocks of organic molecules like bricks?

What is they are like bricks because they come together to form the structure of life?

500

Dehydration synthesis(Condensation)

 What is the design of larger molecules from smaller monomers where a water molecule is released? 

500

What is the difference between saturated and unsaturated? 

What is all single C-C bonds; solid at room temp, while unsaturated is one or more double or triple C-C bonds; liquid at room temp?
