Biochemistry WGU Questions and Answers Already Passed 2 types of bonds in polar interactions Correct Answer- Hydrogen bonds Disulfide bonds 3 major steps in aerobic metabolism Correct Answer- Glyc... olysis Citric acid cycle (CAC) or Kreb's cycle Electron transport chain (ETC) 3 types of amino acids Correct Answer- Hydrophobic Polar Charged 4 parts of an amino acid Correct Answer- Carboxyl group Alpha carbon Amino group R side chain Amino acid sequence wraps around proteins called Correct Answer- Histones At the end of the ETC, ATP is formed when Correct Answer- Protons (H+) in the intermembrane rush through ATP synthase in the inner membrane and into the matrix. ATP Correct Answer- Molecule that fuels our body's activity Bonds in hydrophobic amino acids Correct Answer- C-C, C-HBonds in polar amino acids Correct Answer- O-H N-H S-H Cellular respiration Correct Answer- The process our bodies use to convert food to energy. Chromatin organizes to form Correct Answer- A chromosome Citric acid/ Krebs cycle inputs Correct Answer- Acetyl CoA NAD+ GDP FAD Citric acid/ Krebs cycle location Correct Answer- Matrix Citric acid/ Krebs cycle outputs Correct Answer- CO2 NADH GTP FADH2 Coding strand (DNA) Correct Answer- The original strand off which the new nucleotide sequence is based. Almost the same as mRNA Codominance Correct Answer- A condition in which neither of two alleles of a gene is dominant or recessive. Both phenotypes are expressed.competitive inhibitor Correct Answer- A molecule similar to a substrate that can bind to the enzymes active site. Reversible Increased substrate=increase in reaction Complete dominance Correct Answer- When the phenotypes of the heterozygote and dominant homozygote are indistinguishable. COOI H - C - R I NH3+ Correct Answer- Abbreviated structure (amino acid) Cooperativity Correct Answer- In Hgb, if 1 heme gets filled the other 3 want to get filled. If 1 O2 leaves, the others tend to leave. Cori cycle has a net loss of _________. Correct Answer- 4 ATP Dehydration reaction Correct Answer- Creates a peptide bond by removing water. Disulfide bond Correct Answer- Very strong covalent bond between two sulfur atoms. Can only be broken by chemical agents. DNA polymerase III Correct Answer- synthesizes new DNA only in the 5' to 3' direction Needs a primer to startElectron transport chain inputs Correct Answer- NADH FADH2 O2 ADP + P Electron transport chain location Correct Answer- Inner membrane Electron transport chain outputs Correct Answer- NAD+ FAD H2O ATP Feedback inhibition Correct Answer- When end product is no longer being consumed and starts accumulating, the end product binds with the initial enzyme, stopping it from bonding with the substrate. Reversible Fermentation converts _________ into __________. Correct Answer- NADH, NAD+ and 2 lactates frameshift mutations Correct Answer- Insertions and deletions Glucagon __________ the Glut4 doors. Correct Answer- Closes Glut 4 Correct Answer- Cell doorways for glucose. Glycogenesis Correct Answer- Glucose forms a chain called glycogen. Happens in the liver when it detects insulin.Glycogenolysis Correct Answer- Break down of glycogen to glucose to be released into blood stream. Happens in liver when it detects glucagon. Glycolysis inputs Correct Answer- Glucose 2 ATP 4 ADP 2 NAD+ Glycolysis location Correct Answer- Cytoplasm Glycolysis outputs Correct Answer- 2 pyruvate 2 NADH 4 ATP 2 ADP Helicase Correct Answer- An enzyme that untwists the double helix of DNA at the replication forks. Hemoglobin affinity and location Correct Answer- Lower O2 affinity, picks up O2 in lungs and delivers to body Hemoglobin in muscle-5 qualities Correct Answer- Lower [Show More]
