electron transport

the last electron splits dioxygen
when ox-phos stocks the store of ATP
it's obligate for aerobes such as men
but there're more options lower on the tree
reducing water, sulfate, CO2
depending on their phylum and their class
Archaea would thrive on a witch's brew
but bloat a mammal's gut with noxious gas
methanogens are doing what they must
to spare us hydrogen's toxicity
and some like thermite can reduce mere rust
microbes engaging in metallurgy
you've seen one vertebrate you've seen them all
diversity's the province of the small
