respiration

• describe glycolysis?


  1)glucose phosphorylated using ATP to create glucose phosphate

  2)isomerism occurs and phosphorylation again into fructo-1,2-bisphosphate

  3)then because it is highly reactive it splits into 2 TP molecules

  4)TP is oxidised and turns into pyruvate

  5)NAD is reduced and net gain of 2 ATP
• in anaerobic what is pyruvate converted to?


  lactate or ethanol
• describe the link reaction?


  1)pyruvate is decarboxylated

  2)then oxidised to create acetate while NAD is reduced

  3)acetate combines with coenzyme A forming acetyl coenzyme A

  4) products are carbon dioxide , nadh and acetyl coA
• where do glycolysis and the link reaction take place?


  cytoplasm and matrix

• what type of phosphorylation happens in krebs? 


  substrate-level
• what is oxidative phosphorylation ?


  process where energy is taken from reduced coenzymes to create ATP, involving electron transport chain and chemiosmosis
• what is the terminal electron acceptor in aerobic?


  Oxygen
• how much ATP from 1 glucose?
