The Link Reaction Flashcards

Q
What are the 2 stages of the link reaction?
A
- Pyruvate is dehydrogenated (catalysed by Pyruvate dehydrogenase).
• The H+ ions are accepted by NAD, which is reduced to NADH
• Pyruvate is decarboxylated (catalysed by Pyruvate decarboxylase).
↪️The carboxyl group is released as CO2
• The decarboxylation AND dehydrogenation of Pyruvate forms Acetate (2C)
- CoA binds to the acetate group and carries it to the Krebs cycle as Acetyl CoA
