The flashcards below were created by user kcosen01 on FreezingBlue Flashcards. What would you like to do?


  1. Step 1 to enter TCA cycle
    glucose is converted to pyruvate via glycolysis
  2. Step 2 to enter TCA cycle
    pyruvate is converted to acetyl co-A via pyruvate dehydrogenase

    NAD+ is reduced to NADH
  3. Step 1 of citric acid cycle
    Acetyl co-A is converted to citrate via citrate synthase
  4. Step 2 of TCA 
    citrate --> isocitrate 

    • enzyme: aconitase
    • internal redox, carbon rearrangement
  5. Step 3 of TCA
    isocitrate -> alpha ketoglutarate 

    • enzyme: isocitrate dehydrogenase
    • redox: NAD+ -> NADH 
    • CO2 is produced 
  6. Step 4 TCA
    alpha-ketoglutarate --> succincyl co-A 

    • enzyme: alpha-ketoglutarate dehydrogenase
    • redox: NAD + --> NADH 
    • CO2 is produced 
  7. Step 5 TCA
    succinyl co-A --> succinate 

    • enzyme: succinyl co-A synthetase
    • redox: GDP --> GTP
    • **high
