Meaning of Krebs cycle in English:

Krebs cycle

Pronunciation /krɛbz/


  • The sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.

    ‘For instance, Nelson at one point referred to a scientific paper on the evolution of the Krebs cycle.’
    • ‘The Krebs cycle is part of the energy pathway in all living cells.’
    • ‘Overall, the Krebs cycle provides energy and heat for the body's many processes, and the mitochondria are key to this process.’
    • ‘For example, in 1943, Hans Adolf Krebs was largely responsible for the formulation of the citric acid or Krebs cycle.’
    • ‘Specialized cells known as macrophages rid the body of the implants as carbon dioxide and water re-enter the normal physiological mechanisms at the cellular level via the Krebs cycle.’
