Glycolysis 1 Glycolysis • The Glycolytic pathway describes the oxidation of glucose to pyruvate with the generation of ATP and NADH • It is also called as the Embden-Meyerhof Pathway • Glycolysis is a universal pathway; present in all organisms: from yeast to mammals. Which of the following situations does not result in a breakdown of the proton gradient? Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis. Thus, four ATP molecules are synthesized and two ATP molecules are used during glycolysis, for a net gain of two ATP molecules. Glycolysis is a sequence of ten enzyme-catalyzed reactions. It takes a small input of energy to get the process started, but once it’s started a large amount of energy will eventually be produced. ATP provides the energy. It should be noted that under actual conditions the amount of free energy required for the synthesis of ATP from ADP and P i is much higher than that required under standard conditions, namely, approximately 50% of the energy released is stored within ATP. • In eukaryotes, glycolysis takes place in the cytosol Glycolysis: where the pathway takes place in the cell, steps, enzymes, and products. 1. • In highly active muscle, there is anaerobic glycolysis because the supply of O2cannot keep up with the demand for ATP.
