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 ...

The proton gradients that power respiration are as universal as the genetic code itself, giving an insight into the origin of life and the singular origin of complexity. Why do virtually all cells ...

These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose. Then, via respiration processes, cells use oxygen and glucose to synthesize energy ...

St. Jude researchers reveal that moderate levels of mitochondrial DNA mutations boost leukemia growth by increasing metabolic ...

Lin said that in a hypoxic tumor microenvironment, cancer cells secrete hydrogen sulfide and send a signal to the tetrameric protein pyruvate kinase (PKM2), causing it to break down into smaller ...
