The
pathway
involves
the
oxidative
decarboxylation
of
a
hexose
molecule
to
a
pentose
followed
by
the
rearrangement
of
the
carbon
skeleton
of
the
pentose
produced
.The
reactions
eventually
yield
CO2
and
water
with
the
generation
of
30
mole
of
ATP
per
mole
of
hexose
of
which
one
mole
is
utilised.
This
pathway
is
therefore
energetically
one
of
the
most
important
mechanism
by
which
cells
derive
energy
by
complete
oxidation
of
glucose
to
CO2
and
water
in
addition
to
providing
a
variety
of
intermediates
for
biosynthetic
processes.
