introduction to metabolism

  1. what are the five circulating fuels of metabolism
    • glucose
    • lactate
    • amino acids
    • free fatty acids
    • ketone bodies
  2. what are the key metabolic intermediates?
    • glucose - 6- phosphate
    • pyruvate
    • acetyl CoA
  3. what are the exceptions to metabolism
    • anaerobic metabolism: why? no mitochondria, no ETC
    • plants: uses photosynthesis
    • skeletal muscles undergoing high intensity exercise
  4. removal of which bonds in ATP does not release energy
    Image Upload 1
  5. which bond on ATP molecule produces the most energy
    between gamma and beta
  6. what is the bond between phosphates in ATP
    phosphoanhydride bonds
  7. what are the other high energy phosphate compounds besides ATP
    • 1,3-BPG
    • PEP
    • phosphocreatinine
    • Succinyl CoA
  8. what is substrate level phosphorylation
    substrate level phosphorylation involves phosphate transfer during enzymatic reactions of metabolic pathways
  9. what is oxidative phosphorylation
    • ATP is synthesized using energy produced by reduction of oxygen to water.
    • "ETC"
    • requires NADH and FADH2
  10. what are the reducing electron carriers in metabolism
    • NADH
    • NADPH
    • FADH2
  11. what are the oxidizing electron carriers in metabolism
    • NAD+
    • NADP+
    • FAD
  12. is -G reaction proceeds
    • spontaneously
    • exergonic
  13. +G reaction proceeds
    • non-spontaneously
    • endergonic
  14. increase in concentration of AMP is what kind of signal to a cell
    • low signal
    • causes increase in metabolism
  15. what is another name for myokinase
    adenylate kinase
