Measuring mitochondrial respiration in frozen tissue samples provides the first comprehensive atlas of how aging affects mitochondrial function in mice.

This requires energy. These molecules can be recycled so that a constant stream of energy rich ATP is available for all metabolic pathways in the cell. Almost all cellular processes need ATP to ...

All organisms need ATP to live. Respiration is only around 40 per cent efficient. As animals respire, heat is also released. In birds and mammals, this heat is distributed around the body by the ...

The glycolysis and Krebs cycle metabolic pathways, in aerobic respiration, produce precursors of various important cellular molecules such as the primary metabolite ATP; other metabolic pathways ...
