“The ultimate work of energy production is accomplished not in any specialized organ but in every cell of the body. A living cell, like a flame, burns fuel to produce the energy on which life depends. The analogy is more poetic than precise, for the cell accomplishes its ‘burning’ with only the moderate heat of the body’s normal temperature. Yet all these billions of gently burning little fires spark the energy of life. Should they cease to burn, ‘no heart could beat, no plant could grow upward defying gravity, no amoeba could swim, no sensation could speed along a nerve, no thought could flash in the human brain,’ said the chemist Eugene Rabinowitch.”
