WGU Biochemistry OA Exam Questions And
Correct Answers


Bohr Effect chart (low pH) - answer✔C- High CO2
H- High H+
A- Acidic
R-Release of O2(rt. Shift)
T- tense state (in tissues)

Primary structure - answer✔Sequence of amino acids that make up a protein

Secondary Structure - answer✔Sequence of amino acids fold.

Tertiary Structure - answer✔-more folding in a 3D shape.
-R groups (side chains)

Quaternary Structure - answer✔Protein has more than 1 polypeptide chain.

Chemical reaction - answer✔-absorb and release energy
-activation energy
-energy is released (heat & light) when bonds are broken.

Exothermic reaction - answer✔Exo=to release
Thermo=heat
-chemical reaction that releases more energy than it absorbs (as heat & light)

Example of exothermic reaction - answer✔Cellular respiration- breaks down glucose to make
cellular energy

Endothermic reaction - answer✔Endo=absorb
Thermos=heat

-absorbs more energy than it releases

Example of endothermic reaction - answer✔Photosynthesis- takes in light to break down to
create glucose

Catalyst - answer✔Substance that will decrease the activation energy needed to start a chemical
reaction

Enzymes - answer✔-catalysts used by cells
-increase the rate of chemical reaction
-specific to substrates

Enzyme structure - answer✔-they are proteins
-twist, fold, bend to final shape
-shape attracts specific molecules

Active site - answer✔-location on enzyme where substrate binds

Function of DNA polymerase in process of PCR. - answer✔-increase expression
-2 genes
-SIRT1 & SIRT2

Function of a molecule - answer✔Structural component of the lipid bilayer
How would lipid production in a cell change in order to maintain fluidity of its cell membrane as
it adapts to lower temperatures? - answer✔Produce lipids with shorter fatty acid chains

Function of cholesterol - answer✔Maintains membrane fluidity

Lipid (fat) soluble vitamins - answer✔A, D, E, K

What stimulates beta-oxidation of fatty acids? - answer✔An increase in NAD+ concentration in
the mitochondrial matrix
What occurs in an otherwise healthy person whose diet has very few carbs and high levels of
fats? - answer✔Acetone is produced in the blood

Amino acids - answer✔-Non-polar (hydrophobic)
-Polar charged
