Offprint of Hugo Theorell's Nobel Lecture, December 12, 1955. The Nobel Prize in Physiology or Medicine 1955 was awarded to Axel Hugo Theodor Theorell "for his discoveries concerning the nature and mode of action of oxidation enzymes." "Catalysts are substances that speed up chemical reactions without influencing the end products. Enzymes are catalysts active in biological processes. Hugo Theorell and colleagues investigated how enzymes that promote oxidation reactions are constructed and function. A breakthrough came in 1935 when he demonstrated how a yellow-colored enzyme in yeast had two parts, both of which were crucial to its function. He also explained how iron atoms in many enzymes have an important function in transporting electrons" (Nobel Prize website). Signed by Author(s).
