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


  1. Lactate + NAD+ ---> pyruvate + NADH + H+
    Lactate dehydrogenase
  2. Acetyl CoA + H2O ---> CoA + acetate
    Hydrolysis of acetyl CoA and acyl CoA by water
  3. pyruvate + CoA + NAD+ ---> acetyl CoA + CO2 + NADH + H+
    • Pyruvate dehydrogenase (irrevirsible, therefore cannot make pyruvate from acetyl CoA)
    • 1. not active when phosphorylated
    • 2. active when dephosphorylated
  4. Acetyl CoA + 3NAD+ + FAD (enzyme bound) + GDP + P + 2 H20

    2CO2 + 3NADH + FADH2 (enzyme bound) + GTP + CoA
    • Krebs cycle
    • 1. each NADH yields 3ATP
    • 2. each FADH2 yields 2 ATP
  5. glucose + 2P + 2ADP + 2 NAD

    2 pyruvate + 2 ATP + 2NADH + 2H+ 2 H2O
    Glycolysis
  6. 2 pyruvate + 4 ATP + 2 GTP + 2 NADH + 6 H2O

    glucose + 4 ADP + 2 GDP + 6P + 2 NAD + 2H+
    Gluconeogenesis
