There are multiple theories as to why animals grow old and die. One of the first theories of aging blames free radicals for our eventual demise (Harman, 2003). Free radicals are unstable molecules ...

Cell aggregates have attracted much attention owing to their potential applications in tissue engineering and drug screening. To evaluate cellular respiration of individual cell aggregates in these ...

The high-mobility group box 1 (HMGB1) protein has a central role in immunological antitumour defense. Here we show that natural killer cell-derived HMGB1 directly eliminates cancer cells by triggering ...

The importance of ΔNp63 in controlling metabolism has not been investigated so far. We identified a regulatory pathway involving ΔNp63 and the glycolytic enzyme hexokinase 2 (HK2). ΔNp63 ...

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 ...

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 ...

Recent studies from the field of interoception have highlighted the link between bodily and neural rhythms during action, perception, and cognition. The mechanisms underlying functional body-brain ...

Photosynthesis is a biological process used by many organisms to convert light energy into chemical energy, which is stored in organic compounds that can later be metabolized through cellular ...

Metabolism close metabolismAll the chemical reactions in the cells of an organism, including respiration. is the term used for all the chemical reactions that happen inside an organism's body. Starch ...

Humans haven’t yet figured out how to turn energy from the sun into chemical energy, or how to use that energy to support life—but producers have. From the basic parts of the cell to isolating the ...

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, ...
