Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO 2 and water—a process during which the energy-rich molecule ATP is produced. Cells ...

The proton gradients that power respiration are as universal as the genetic code itself, giving an insight into the origin of life and the singular origin of complexity. Why do virtually all cells ...

Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of ...

This video explains how living things use cellular respiration to produce energy. Aerobic respiration uses oxygen to break down glucose completely. Anaerobic respiration converts oxygen to lactic acid ...

Researchers in Oslo and Athens report that the small molecule phenazine methosulfate functions as a chemical “redox bypass”, ...
