Detailed explanation-1: -Glycolysis is the metabolic pathway that converts glucose (C 6H 12O 6) into pyruvate. The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). Glycolysis is a sequence of ten reactions catalyzed by enzymes.
Detailed explanation-2: -Glycolysis involves the breaking of sugar molecules to release energy that is required for cellular metabolism. It occurs in the cytoplasm of the cell. The main aim of glycolysis is to synthesize thousands of ATP molecules used for various cellular metabolism.
Detailed explanation-3: -Glycolysis is important because it is the metabolic pathway through which glucose generates cellular energy. Glucose is the most important source of energy for all living organisms. In the human body, glucose is the preferred fuel for the vast majority of cells: It is the only fuel red blood cells can use.
Detailed explanation-4: -The function of glycolysis in cellular respiration is to break down one molecule of glucose into two molecules of pyruvic acid. These pyruvic acid molecules will then be converted into acetyl-CoA molecules and enter the citric acid cycle.
Detailed explanation-5: -Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.
