Glycolysis actively transports
Pyruvate
+
Reduced NAD
into the
matrix
for the link reaction
Pyruvate is decarboxylated by
pyruvate decarboxylase
releasing
CO2
and is oxidised into
acetate
by
pyruvate dehydrogenase
forming
reduced NAD
Acetate from the link reaction is combined with
coenzyme
A
creating
AcetylCoA
Net Gain of Link Reaction Per Pyruvate = 2x Reduced
NAD
+
CO2
