Scientists Reveal Hidden Machinery of Mitochondria in Stunning Detail
27th March 2025
Mitochondria, often called the powerhouses of the cell, are responsible for producing the energy needed for nearly all vital cellular processes. Researchers at the University of Basel in Switzerland have now used cryo-electron tomography to study mitochondria in unprecedented detail, revealing new insights into their inner structure.
Their findings show that the proteins responsible for generating energy, known as respiratory complexes, do not work alone. Instead, they assemble into large structures called “supercomplexes,” which play a key role in efficiently producing ATP, the cell’s primary energy source.
