Introduction to Metabolism

• Oxidative phosphorylation


  ATP is produced by harnessing energy from the ETC
• Substrate level phosphorylation


  ATP is produced by harnessing energy from a substrate
• Kinases


  Catalyses a phosphorylation reaction
• Phosphatases


  Catalyses a dephosphorylation reaction
• Phosphorylases


  Catalyses a phosphorolysis reaction
• Synthases


  Catalyses condensation reactions that don't require a nucleotide triphosphate
• Synthetases


  Catalyse condensation reactions that require a nucleotide triphosphate
• Dehydrogenases


  Catalyse oxidation reduction reactions
• Dehydrogenases are named according to?

  The substrate oxidised
• NAD+ takes...


  one proton and two electrons, leaving a H+ in solution
• FAD takes...


  two protons and two electrons
• CoA is really big with lots of charges, meaning...

  it won't diffuse across membranes
• Which unit on CoA is easily recognised by enzymes?

  Pantothenate unit
• How are fatty acids stored in adipose tissue?

  As triglycerides
• How are fatty acids broken down into acetate?

  Beta-oxidation
