WGU Biochemistry OA
2, 3, BPG - CORRECT ANSWER ✅: -produced in our body naturally
-similar function to H+ (stabilizes the T state)
-produced in 2 cases (high altitudes & pregnancy)
Acetyl CoA - CORRECT ANSWER ✅: -2 carbons
-attached to coenzyme A (to make sticky we need biotin)
Active site - CORRECT ANSWER ✅: -location on enzyme where substrate binds
Aggregation - CORRECT ANSWER ✅: -proteins clump together in abnormal way (d/t
hydrophobic interactions)
Amino acid - CORRECT ANSWER ✅: -has amino group (-NH2)
-& a carbonyl group (-COOH)
-cx. Based on side chains
Anneal - CORRECT ANSWER ✅: -step 2 of PCR
-use DNA primers that match the gene to find only the gene we want (ex: to find BRCA gene)
Are enzymes specific? - CORRECT ANSWER ✅: Yes
Assuming 100% reaction efficiency, how many DNA copies are created after the completion of
4 complete PCR cycles? - CORRECT ANSWER ✅: 16
Base excision repair - CORRECT ANSWER ✅: -only 1 nucleotide damaged
- remove and replace
Beta oxidation - CORRECT ANSWER ✅: -breakdown of fats
-occurs when we eat fats, or exercise
-break beta bonds
Beta oxidation - CORRECT ANSWER ✅: Break fats into acetyl CoA
Bohr Effect chart (low pH) - CORRECT ANSWER ✅: C- High CO2
, H- High H+
A- Acidic
R-Release of O2(rt. Shift)
T- tense state (in tissues)
Carbohydrates - CORRECT ANSWER ✅: -linear
-CH2O formula
-energy=glucose
-structure=cellulose
Catalyst - CORRECT ANSWER ✅: Substance that will decrease the activation energy needed
to start a chemical reaction
Chaperones - CORRECT ANSWER ✅: Help fold proteins
Chemical reaction - CORRECT ANSWER ✅: -absorb and release energy
-activation energy
-energy is released (heat & light) when bonds are broken.
CO - CORRECT ANSWER ✅: -carbon monoxide (1 O2)
-poison!
-binds to hgb on the heme & blocks O2 from binding
-has 200 x higher affinity
-a competitive inhibitor
-puts hgb into the R state (makes hgb want to bind hgb even more)
-this is why it is so dangerous, our hgb picks it up instead of O2)
Competitive inhibition - CORRECT ANSWER ✅: -medicine/drugs
-competitive inhibitor will bind to active site to prevent substrate from binding
