So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

Ancient microbes illustrate a particular kind of respiration in which carbon dioxide and hydrogen are combined to form acetic ...

Scientists at Goethe University uncover how the oldest enzyme in cellular respiration functions – opening the door to ...

In this episode of Crash Course Botany, we’ll explore how the processes of photosynthesis and cellular respiration work, why they’re so critical for all life on Earth, and how they’re ...

VOICEOVER: Anaerobic respiration in micro-organisms. All living cells respire. It's the process that releases the energy stored in glucose for life processes, such as growth. Unlike aerobic ...

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 ...

Redox reactions form the basis of many fundamental processes of life. Without them, neither cellular respiration nor ...

as might be expected for a process that is critical to the survival of all life on Earth. Nitrification is the process that converts ammonia to nitrite and then to nitrate and is another important ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a ...

They form the basis of many fundamental processes in life. Without them, cell respiration and photosynthesis would be impossible. Redox reactions also ...
