But it involves both anabolism (synthesis) and catabolism (breakdown). 11. Glycolysis. Glycolysis is the central pathway for the glucose catabolism in which glucose (6-carbon compound) is converted into pyruvate (3-carbon compound) through a sequence of 10 steps. Answered; ... Glycolysis is also called the EMP pathway because the steps of this biochemical pathway were worked out by the German scientists Gustav Embden, Otto Meyerhof and Jakub Parnas in 1930s; Glycolysis is the common pathway seen in both aerobic and anaerobic respiration. At this point in the glycolytic pathway, we have two 3-carbon molecules, but have not yet fully converted glucose into pyruvate. Fructose in the liver can be converted to. It is a cyclic pathway. Glycolysis serves two primary intracellular functions: Produce ATP and intermediate metabolites to serve different pathways.
