●● What are the major functions of a carbohydrate?
Answer: Energy storage molecule, acting as signal between cells, acting
as a structural molecule to help define cell shape, and acting as a
component of a cell membrane
●● What are the major functions of lipids?
Answer: Acting as signals between cells, acting as an energy storage
molecule, excludes large or highly charged molecules from entering or
exiting cells, component of cell membrane (phospholipid bi-layer)
●● What is the major function of a nucleic acid?
Answer: Information storage molecule
●● Which of the following is not a polymer made up of individual
monomers?
A) Carbs
B) Proteins
C) Fatty Acids
D) Nucleic Acids
,Answer: C
●● Which of these statements is true?
A) Almost all organisms have a phospholipid bilayer that makes up a
major component of their cell membrane
B) Almost all organisms use the same 4 nucleotides to encode their
genetic information
C) Almost all organisms use the same 20 amino acids to create proteins
D) Almost all organisms use carbs as an energy source
E) All of the above
Answer: E
●● Peptide Bond
Answer: forms between the carboxyl group of one amino acid and the
amino group of another amino acid
●● What type of interaction stabilizes the a-helix and the B-pleated
sheet of proteins?
Answer: Hydrogen bonds
●● What type of interaction is directly responsible for the formation of
secondary structure?
Answer: Hydrogen bonds between sections of the polypeptide backbone
, ●● The tertiary structure of a protein is
Answer: unique 3 dimensional shape of the fully folded polypeptide
●● All covalent bonds in a protein are disrupted, what level of structure
is preserved?
Answer: No protein structure
●● Sodium channels are proteins that control the passage of sodium ions
across the cell membrane. The protein forms a pore, or opening, in the
membrane. You isolate what you think are two different molecules of
sodium channel, and determine that one of the proteins has a smaller
pore diameter than the second therefore allows fewer sodium ions to
cross the membrane than the other. which of the following do you
conclude?
A) These two sodium channels likely have different primary structures
B) These two sodium channels likely have different secondary structures
C) These two sodium channels likely have different tertiary structures
D) All of the above
Answer: D
●● Nucleic Acids are made up of what
Answer: Nucleotides
