Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life, into the foreground.

Water is life's matter and matrix, mother and medium. There is no life without water.

This oxidation of hydrogen in stages seems to be one of the basic principles of biological oxidation.

The foodstuff, carbohydrate, is essentially a packet of hydrogen, a hydrogen supplier, a hydrogen donor, and the main event during its combustion is the splitting off of hydrogen.

Water is life's mater and matrix, mother and medium. There is no life without water.

Without energy life would be extinguished instantaneously, and the cellular fabric would collapse.
