Researchers reveal molecular structures involved in plant respiration

All plants and animals respire, releasing energy from food. At the cellular level, this process occurs in the mitochondria. But there are differences at the molecular level between how plants and animals extract energy from ...

Structure of a mitochondrial ATP synthase

ATP synthase is a universal molecular machine for energy conversion. By coupling to cellular respiration in mitochondria, it catalyzes conversion of chemical energy of cells.

Reenergizing antibiotics in the war against infections

Antibiotics are the mainstay in the treatment of bacterial infections, and together with vaccines, have enabled the near eradication of infectious diseases like tuberculosis, at least in developed countries. However, the ...

DNA damage: The dark side of respiration

(Phys.org) —Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at LMU now report how byproducts of respiration cause mispairing ...

Common fungicide wreaks havoc on freshwater ecosystems

Chlorothalonil, one of the world's most common fungicides used pervasively on food crops and golf courses, was lethal to a wide variety of freshwater organisms in a new study, University of South Florida researchers said ...

Cellular metabolism self-adapts to protect against free radicals

Oxygen-consuming organisms obtain energy through cellular respiration, which is the transformation of carbohydrates and oxygen into carbon dioxide and water. This process also produces toxic oxygen radicals which must be ...
