Glycolysis
of
glucose
produces
reduced NAD
,
pyruvate
and a
net gain
of
ATP.
Pyruvate
is
reduced
to
ethanol
using
hydrogen
from
reduced NAD.
Carbon dioxide
is also
formed
during the
reaction.
KEY POINT: the
oxidised NAD
reformed in this way can be used in further
glycolysis
(otherwise the cell would
run out
of NAD).
