Hans Krebs

Hans Krebs was a German-born British biochemist renowned for discovering the Krebs cycle, also known as the citric acid cycle. This is a vital process occurring in our cells' mitochondria, where nutrients like carbohydrates, fats, and proteins are broken down to produce energy. The Krebs cycle is a central part of cellular respiration, enabling cells to generate the power needed for various functions. His work significantly advanced our understanding of metabolism and energy production, earning him the Nobel Prize in Physiology or Medicine in 1953.
