Peter W. Mitchell

Peter W. Mitchell was a biochemist who discovered chemiosmosis, a process vital for how cells produce energy. He showed that mitochondria (the cell's power plants) generate energy by a flow of charged particles across their membranes, creating a form of chemical "currency" called ATP. His work revolutionized our understanding of cellular energy production and earned him the Nobel Prize in Physiology or Medicine in 1978. Mitchell’s discovery explained how cells efficiently convert nutrients into usable energy, influencing treatments for metabolic diseases and advancing biological sciences.
