Earth Science: Carbon – Enzymes: active catalysts The most important role in the metabolism of living organisms is played by enzymes, which catalyze billions of metabolic reactions every second. In 1878, the German physiologist Wilhelm Kuhne (1837-1900) introduced the term “enzyme.” At that time, the word “ferment” was being used. Alcoholic fermentation had been known … Read more

Earth Science: Cells – Further Metabolic Processes Cell metabolism involves the transport of electrons in a multistep process utilizing oxygen (aerobic) or in a less efficient process of fermentation without the use of oxygen (anaerobic). The cell’s metabolic processes, such as the breakdown of glucose (glycolysis) and the citric acid cycle, lead to the formation … Read more
