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 ...

Respiration is a series of reactions, but this summarises the overall process. Human muscle can respire anaerobically for short periods of time - even though the process is relatively inefficient, ...

Researchers in Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ...

The origin of oxygenic photosynthesis in Cyanobacteria led to the rise of oxygen on Earth ~2.3 billion years ago, profoundly altering the course of evolution by facilitating the development of aerobic ...

Atmospheric oxygen both enables complex life and is a hallmark of it. Aerobic respiration is so energetically efficient that it’s thought to have been needed for multicellularity. There is hardly any ...

Respiration close respirationA chemical reaction that occurs in the mitochondria of cells in which glucose and oxygen react to produce carbon dioxide and water, releasing energy. is a chemical ...
