What is true for E. coli...

In the old joke a person is not "dead", they are just "metabolically different". Here, though, is evidence that organisms from microbe to elephant are metabolically the same (or pretty close):
"The largest organism we studied is the elephant, which has a metabolic rate of 1 Watt per kilogram, and the smallest is a bacterium with a metabolic rate of 4 Watts/kg"... Using the formulae that had previously been used to calculate the metabolic rate within separate classes of animals, you would have expected a multimillion-fold difference.
-- Is there an optimum speed of life?
