Link Reaction

• What does the link reaction do?

  converts pyruvate to acetyl coenzyme A
• What happens to pyruvate in the Link Reaction?

  -Decarboxylated (one carbon atom removed in the form of CO2)

  -Oxidised
• Pyruvate is oxidised to form what?

  Acetate and NAD is reduced to form reduced NAD
• What is acetyl combined with?

  CoA to form acetyl CoA
• is ATP produced in the link reaction?

  no
• What does acetyl CoA stand for?

  acetyl coenzyme A
• what does CoA stand for?

  coenzyme A
• How much does the link reaction occur?

  twice for every glucose molecule
• What is made for every glucose molecule that enters glycolysis?

  2 pyruvate molecules

  • this means the link reaction and the Krebs cycle happen TWICE FOR EVERY GLUCOSE MOLECULE
• For every glucose molecule:

  • 2 molecules of acetyl CoA go into Krebs
  • 2 CO2 molecules released as a waste product of respiration
  • 2 molecules of reduced NAD formed and go to oxidative phosphorylation
