cohesion

What type of bond connects atoms together in a single molecule of water?

polar covalent

Which type of biomolecule is this?

carbohydrate

What does "high heat capacity" mean?

a substance can absorb (or lose) large amount of thermal energy without changing temperature

The complete three-dimensional structure of a polypeptide is the ___ structure of proteins.

tertiary

Name one function for this class of biomolecule.

denaturation; denaturing

What type of biomolecule is this?

lipid (phospholipid)

What does "polar" mean?

having charges unevenly distributed (a positive end and a negative end)

Which two properties of water allow it to move up within the stem of a plant?

adhesion and cohesion

What type of biomolecule is this?

lipid (triglyceride)

Proteins like hemoglobin require multiple subunits to interact; this is the ___ structure of proteins.

quaternary

Which class of biomolecules are generally hydrophobic?
