A team of international researchers led by Karolinska Institutet has revealed in unprecedented detail how tetracycline ...

Ubiquinone, a metabolite critical to generating energy in cells, has long been thought to be the only mitochondrial electron transport chain carrier in mammals. Although other electron transporters ...

The cells’ mitochondria skip a key metabolic reaction that takes place in other cells in the body, a study finds. Created by editing the gray wolf genome, two dire wolves are the subject of ...

These are mitochondria of several distantly related unicellular eukaryotes (protists) that lack an electron transport chain altogether. They synthesize ATP from pyruvate breakdown via simple ...

At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this ...
