Definition: Glycolysis is defined as the sequence of reactions metabolizing one molecule of glucose to two molecules of pyruvate or lactate with the simultaneous generation of adenosine triphosphate (ATP). Glycolysis occurs in the cytoplasm. Glycolysis is also known as Embden-Meyerhof-Parnas (EMP) pathway. Glycolysis can occur aerobically as well as anaerobically. Aerobic glycolysis occurs in the presence of oxygen and produces two molecules of pyruvate. Anaerobic glycolysis occurs in the absence of oxygen or when limited amounts of oxygen are available and it produces two molecules of lactate. Features: It occurs mainly in the muscle and liver. It is a major pathway for ATP synthesis in tissues that lack mitochondria. Example - cornea, lens, red blood cells. The sub-cellular site is the cytoplasm. It is very essential for the brain which is dependent only on glucose for energy. The reaction of glycolysis can be divided into two main phases - The preparatory phase (step 1 to step 5...
