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 have found that the protein Stat3 plays a key role in regulating mitochondria, the energy-producing machines of cells. This discovery could one day lead to the development of new ...

Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the ...

Tuberculosis (TB) is a confounding scourge. It's the leading cause of death from infectious disease in the world, and yet it's estimated that those deaths represent perhaps 5% of infections with ...

In the first billion years, there was no oxygen on Earth. Life developed in an anoxic environment. Early bacteria probably obtained their energy by breaking down various substances by means of ...

In obese individuals, endurance exercise improves fitness and increases the number of mitochondria and cellular respiration in skeletal muscles. However, the intervention has no effect on cellular ...

An expert on carbohydrate transport, Kornberg contributed to the discovery of several metabolic cycles in microorganisms during his seven-decade career. Mitochondria age differently depending upon ...

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 ...
