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 ...

Cellular respiration refers to the breakdown of glucose and other respiratory substrates to make energy carrying molecules called ATP. Test your understanding of this process now.

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 ...

Mitochondria are double membrane bound cytoplasmic organelles present in most eukaryotic cells. They are responsible for aerobic respiration, producing energy for the cell, which they achieve through ...

Can the process of aging be delayed or even reversed? Research has shown that, in human cell lines at least, it can. They also found that the regulation of two genes involved with the production of ...

In this study biokinetic and microbial growth coefficients for nitrate versus oxygen respiration in the activated sludge process were evaluated and compared. Two bench-scale activated sludge units ...

Nitric oxide (NO) plays an important role as an inter- and intra-cellular messenger, acting in the cardiovascular system, in the nervous system and as a component of the immune system 1. NO is a ...
