WGU BIOCHEMISTRY OA EXAM
QUESTIONS AND VERIFIED
ANSWERS||2025 UPDATE




What directly provides the energy necessary for the conversion of ADP
to ATP by ATP synthase? - CORRECT-ANSWER-Protons moving down a
concentration gradient from the intermembrane space to the
mitochondrial matrix.




Cori Cycle - CORRECT-ANSWER--muscle cells produce lactate which is
then converted to glucose in the liver




Exonuclease - CORRECT-ANSWER-During DNA replication, if an error is
detected, DNA polymerase removes the nucleotides and replaces them
with correct ones.




Glyco/ gluco - CORRECT-ANSWER-Glucose

,Genesis - CORRECT-ANSWER-Make




Lysis - CORRECT-ANSWER-Break




Neo - CORRECT-ANSWER-New




Insulin - CORRECT-ANSWER--increase glucose in blood

-fed state(after we eat, increase glucose=pancreas releases insulin)

-lets glucose into cells

-signals for GluT4 to go to cell membrane




Glycolysis - CORRECT-ANSWER--break glucose

-make ATP (useable energy)

,Glycogenesis - CORRECT-ANSWER--store glucose as glycogen (short
term storage)

-in liver




Fatty acid synthesis - CORRECT-ANSWER-- make fat from acetyl CoA

-fats stored in triglycerides (3 fatty acids)

-adipose tissue (long term storage)




Glycogenolysis - CORRECT-ANSWER-Break glucose out of glycogen




Gluconeogenesis - CORRECT-ANSWER--make new glucose(from lactate)

-acetyl CoA~pyruvate~glucose

-glycerol (from triglycerides)

-amino acids(last resort!)

, Beta oxidation - CORRECT-ANSWER-Break fats into acetyl CoA




Fatty acid structures - CORRECT-ANSWER--made up of carbonyl groups




Saturated fatty acids - CORRECT-ANSWER--no double bonds

-maximum Hs




Unsaturated fatty acid - CORRECT-ANSWER--(not saturated with Hs)

-at least 1 double bond

-lose 2 Hs per double bond




Essential - CORRECT-ANSWER--we have to eat it (our bodies cannot
make it)

-omega 3

-omega 6

- essential for building other types of lipids
