An ecosystem is like a great organism in that
the species in it behave in a man
Classic Experiment by Englemann in 1882
Thomas Moore, biochemist, says
Photosynthesis creates unequal
gradientsbuildup of positively charged ions
inside thylakoid membrane
The charges on either side of membrane want
to recombine, to release
30% of genes of Mycoplasma genitalium
encode membrane proteins!
Cell biologist Bruce Lipton says our lives are
not ruled by our genes but by our cell
membranes which respond to our thoughts.
