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 ...

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 ...

IN “his Croonian Lecture on the “Mechanisms of Cellular Respiration” delivered to the Royal Society on December 13, Prof. D. Keilin, Quick professor of biology and director of the Molteno Institute in ...

Contrary to accepted knowledge, blood can bring more oxygen to mice brains when they exercise because the increased respiration packs more oxygen into the hemoglobin, according to an international ...

Figure 1: A schematic overview of glycolysis and oxidative phosphorylation. Figure 4: Temperature does not influence the OCR of C. elegans. Figure 5: A schematic overview of an XF respirometer ...

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.

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 ...

The effect of O2 partial pressure on the germination and the respiration of 12 cultivated species was studied. The reciprocal of the time necessary to observe rootlet emergence in 50% of the seeds was ...

Cheyne-Stokes respiration, or periodic respiration, involves an atypical pattern of breathing. It consists of cycles of deep breathing followed by shallow breathing. Cheyne-Stokes breathing can be a ...
