The single-celled ciliated organism Tetrahymena uses a different set of proteins for respiration from plants, animals or yeast, a new study shows. The findings reveal unsuspected diversity in how ...

Many cells can use oxygen or nutrients to generate fuel, and the process is similar in many organisms that use an electron transport chain. But scientists have found that in a tiny organism, things ...

Cellular respiration occurs through the mitochondrial electron transport chain and is responsible for the majority of ATP synthesis in the cell. This process, oxidative phosphorylation, is carried out ...

New research provides the first-ever, atomic-level, 3D structure of the largest protein complex (complex I) involved in the plant mitochondrial electron transport chain. The results could unlock new ...
