Using carbon dioxide the chemical formula
often given for carbon
fixation is...
6CO2 + 12H2O - C6H12O6 + 6O2 + 6H20

but in principle, carbon monoxide could be
used as follows:

6CO + 12H2O -C6H12O6 + 3O2 + 6H2O

I know the Calvin process is complicated
and involves many intermediate
steps (and these intermediate steps may be
impossible with CO).

My question: Has any research been done
involving plants in an
atmosphere of CO? Or has the assumption
been made that it just won't
work?

Thanks.


Maybe CO binds with Mg compounds
irreversibly, just as it does with Fe in
heme.

It is the irreversibility that is the
problem.
