BIBC 120 Metabolism

  1. brief outline of glucose metabolism
    glucose > glucose 6 phosphate > [glycolysis] > pyruvate > [PDH complex] > acetyl CoA > [citric acid cycle] > energy
  2. What happens to amino acids when energy is needed?
    • 1. Amino acids > [oxidation] > ATP
    • 2. Amino acids > [gluconeogenesis] > glucose > ATP
  3. Where do amino acids get converted into glucose?
    liver
  4. What happens to amino acids when protein and energy needs have been met?
    Amino acids get converted to fatty acids and stored in adipose tissue
  5. What is the intermediate of the citric acid cycle that ties into gluconeogenesis?
    oxaloacetate
  6. Amino acid + α-keto acid -->
    glutamate + α-keto acid
  7. water + glutamate -->
    ammonia + α-ketoglutarate
  8. What happens to ammonia?
    ammonia > urea cycle > urea > excreted in urine
  9. order the lipoproteins from lowest to highest density
    chylomicron, VLDL, IDL, LDL, HDL
  10. What is the difference between low-density and high-density lipoproteins?
    low-density has more triglycerides and high-density has more proteins
  11. kcal per gram of carbohydrates
    4 kcal
  12. kcal per gram of fatty acids
    9 kcal
  13. kcal per gram of protein
    4 kcal
  14. ATP per 6-carbon glucose
    30-32 ATP per glucose (5.3 ATP per carbon)
  15. ATP per 16-carbon saturated fatty acid
    106 ATP (6.6 ATP per carbon)
  16. ATP per amino acid
    varies
