Sir Hans Krebs and the Krebs Cycle

Sir Hans Adolf Krebs was born in Hildesheim, Germany, in 1900. He studied medicine, following in his father’s footsteps, but chose a career in scientific research rather than medical practice.

Krebs joined the University of Sheffield in 1935. In 1953, he received the Nobel Prize in Physiology or Medicine for his discovery of the citric acid cycle, now widely known as the Krebs cycle. The cycle explains how cells release energy from nutrients and is a fundamental part of metabolism.

In this video, discover how the Krebs cycle works, why Sir Hans Krebs’ research changed our understanding of how cells use energy, and how his work continues to influence research at the University of Sheffield today.
