Catabolic - Similar, Anabolic - Has Great Variation
Catabolic processes to get ATP, are reasonably similar:
" A bewildering array of chemical reactions occur in any living cell.
Yet the principles that govern metabolism are the same in all
organisms, a result of their common evolutionary origin and the
constraints of the laws of the thermodynamics. In fact, many of the
specific reactions of metabolism are common to all organisms, with
variations due primarily to differences in the source of the free
energy that supports them." Voet, Voet, Pratt, Fundamentals of
Biochemistry Upgrade Ed. p. 354.
But anabolic uses of that ATP range from transport work, mechanical
work, to chemical work. That suggests that the anabolic uses have
evolved to a great variety of processes.
It seems that we have separate catabolic and anabolic processes. And
while catabolic processes to get ATP are somewhat conserved and
similar, the anabolic processes that use that ATP seem more variable |
