UCONN ECE EXAM: BIOLOGY QUESTIONS
Structure of an amino acid - Answers :Amino group, carboxyl group, R group
The permeability of the phospholipid bilayer is determined by? - Answers :The number
of saturated fatty acids, integral proteins in the membrane, and temperature
Primary protein structure - Answers :Sequence chain of amino acids
Secondary protein structure - Answers :Sequence of amino acids are linked by
hydrogen bonds
Tertiary protein structure - Answers :Certain attractions are present between alpha
helices and pleated sheets
Quaternary protein structure - Answers :Multiple amino acid chains
Where is energy in ATP stored? - Answers :The bond between the second and third
phosphate
Allosteric activation - Answers :Active site becomes available to the substrates when a
regulatory molecule binds to a different site on the enzyme.
Allosteric deactivation - Answers :The active site becomes unavailable to the substrates
when a regulatory molecule binds to a different site on the enzyme.
What is active transport? - Answers :Transport that uses energy via phosphorylation(ex.
Na/K pump)
OIL RIG - Answers :Oxidation is losing, reduction is gaining
What makes a molecule polar? - Answers :Uneven charge
What makes a molecule hydrophobic and hydrophillic? - Answers :Oxygen to hydrogen
bonds makes a molecule hydrophillic (likes water)
DNA Replication - Answers :
, A and G are: - Answers :Purines
T and C and U are: - Answers :Pyrimidines
What is the role of NADH and FADH2 in cellular respiration? - Answers :They are
electron carriers, which travel down the electron transport chain during ETC
What is meant by, "the genetic code is redundant but unambiguous?" - Answers :A
single amino acid may be coded for by more than one codon.
Lac operon - Answers :
Hypertonic - Answers :Greater concentration of solute (cell shrinks)
Isotonic - Answers :Cell stays the same
Hypotonic - Answers :Lower concentration of solute (cell swells)
Histone Acetylation - Answers :When histone proteins spread out and uncoil.
Encourages the transcription of DNA
How is the surface area to volume ratio increased? - Answers :By folding, branching,
flattening, etc.
