krebs cycle

• where does the krebs cycle take place?

  matrix
• what conditions does the krebs cycle take place under?

  only aerobic
• what enters the krebs cycle?

  acetylcoenzyme A, NAD, FAD and ADP+Pi
• what exits the krebs cycle?

  acetylcoenzyme A, ATP, CO2, reduced NAD and FAD
• what does acetylcoenzyme A combine with to make?

  combines with a 4C molecule to make a 6C molecule
• what regenerates?

  coenzyme A
• where does coenzyme A go back to when it regenerates?

  the link reaction
• what is lost when the 4C molecule combines with acetylcoenzyme A?

  carbon dioxide
• How is ATP generated?

  substrate level phosphorylation
• what is produced when hydrogen is lost?

  reduced NAD
• what reactions convert a 6C molecule into a 4C again?

  oxidation and reduction
• importance of the krebs cycle:

  produces hydrogen atoms which reduce the coenzymes for oxidative phosphorylation

  generates some ATP
