Q

What occurs in the link reaction between Glycolysis and Krebs cycle/ TCA cycle?

A

A Pyruvate molecule is converted into Acetyl-CoA via a Pyruvate dehydrogenase complex

  • Decarboxylation, CO2 evolved

Q

What occurs in the TCA cycle?

A

Acetyle- Co A(2c) joins with Oxaloacetate molecule (4c)

Form Citric Acid (6c)

Citrate is then decarboxylated twice to give off 2 CO2 molecules
