A team of scientists have elucidated an ancient mechanism of cellular respiration. To that end, they studied bacteria that feed on the gases carbon dioxide and hydrogen, and turn them into acetic ...

With so much hydrogen around, free oxygen could not ... component of ATP (adenosine triphosphate), an energy-carrier in cell respiration. Miller's work showed that compounds necessary for life ...

suggest that a special form of respiration could have existed even then. These microorganisms "respire" carbon dioxide and ...

We often think of animals using oxygen and glucose for cellular respiration and producing carbon dioxide ... As this acid forms, it breaks down (dissociates) into a hydrogen ion and a bicarbonate ion.

hydrogen and oxygen, Keller began exploring whether various combinations of these compounds could support growth, ...

The proton gradients that power respiration are as universal as the ... Why do virtually all cells "breathe" by pumping protons (hydrogen ions) across a membrane? According to molecular biologist ...
