Biochemistry Test 1 Questions and
Answers Graded A+
biochemistry ✔✔a discipline in biochemistry; is the description of molecules in
biology/chemistry of proteins
molecular biology ✔✔a discipline in biochemistry; the manipulation of DNA, genetics
cell biology ✔✔a discipline in biochemistry; larger scale, functions and mechanisms within a
cell/cell energetics
cellulose ✔✔a natural polymer; found in plants for storage
glycogen ✔✔a natural polymer; found in animals for storage
protein ✔✔a natural polymer; tightly linked bonds
nucleotide ✔✔a natural polymer; covalent bonds
,C,H,N,O,S ✔✔chemical elements commonly found in biochemistry
carbon ✔✔an element commonly found in biochemistry, creates strong single or double bonds
with very little rotation
covalent ✔✔a chemical bond in biology; a pair of shared electrons, very strong, bonds between
polymers, >1 bond per atom, flexible and alternate re-arrangement
non-covalent ✔✔a chemical bond in biology; weaker bonds, but additive, creates specificity,
highly dynamic/transient bonds, required for molecular recognition
electrostatic, hydrogen, van der waals, hydrophobic ✔✔4 types of non-covalent interactions
electrostatic ✔✔a non-covalent interaction; such as ionic bonds Na⁺ + Cl⁻ -> NaCl
hydrogen ✔✔a non-covalent interaction; a H is shared between two electronegative atoms such
as F,O, or N; the more electronegative atom pulls the electron closer, creating a dipole
, donor acceptor ✔✔the H bond _____ becomes more tightly linked, the H bond_____becomes
less tightly linked (two answers separated by a space please)
Van Der Waals ✔✔a non-covalent interaction; the interaction between molecules with
temporary dipoles from fluctuating electrons, are weak but additive
hydrophobic interaction ✔✔a non-covalent interaction; the clustering of these molecules in polar
substances i.e. water interacts with itself and causes other non-polar residues to cluster
biological solvent ✔✔roles of water; many organic and biological materials are able to dissolve
in water
part of reaction ✔✔roles of water; water is a common substance in biochemical reactions such as
the cleavage of bonds
regulation ✔✔roles of water; water is essential in regulating temperature and pH (the ideal
temperature of water with the highest heat capacity is 37°C)
