CHEM 210 BIOCHEMISTRY UPDATED ACTUAL
EXAM QUESTIONS AND CORRECT
ANSWERS FULL SOLUTION GRADED A+
◉ macromolecule/polymer. Answer: a large molecule composed of
many smaller molecules known as monomers
◉ acid. Answer: a solution with a pH below 7.0 (has more dissolved
hydronium ions than hydroxide ions)
◉ base. Answer: a solution with a pH above 7.0 (has more dissolved
hydroxide ions than hydronium ions)
◉ biochemistry. Answer: study of the chemistry of life
◉ amino acid. Answer: the monomers (subunit molecules) that
compose proteins
◉ nucleotide. Answer: the monomers (subunit molecules) that
compose nucleic acids
◉ fatty acids/glycerol. Answer: the monomers (subunit molecules)
that compose lipids
, ◉ monosaccharride (glucose, fructose, and galactose). Answer: the
monomers (subunit molecules) that compose carbohydrates
◉ ionic bond. Answer: a bond that is characterized by electron
borrowing (transferring)
◉ covalent bond. Answer: a bond that is characterized by electron
sharing
◉ hydrogen bond. Answer: a bond that is a result of the polarity that
exists between some types of molecules (e.g. water molecules)
◉ polar. Answer: a term that describes a molecule with an unequal
balance of charge
◉ cohesion. Answer: attractive force that describes water's tendency
to stick to other water molecules
◉ adhesion. Answer: attractive force that describes water's tendency
to stick to unlike surfaces
◉ capillarity. Answer: water's ability to move up a narrow opening
against the force of gravity
◉ protein. Answer: macromolecule group that is used for body
structure and cell repair
