Energy investment in the first stage of glycolysis requires glucose to be phosphorylated and cleaved to yield two molecules.
Glycolysis is a metabolic pathway that converts glucose into two molecules of pyruvate in the presence of oxygen or two molecules of lactate in the absence of oxygen.
The metabolic pathway that converts glucose to pyruvate is known as glycolysis. This free energy is used to create the high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide. Glycolysis is a series of ten enzyme-catalyzed reactions. The process occurs in a cell's cytoplasm and does not require oxygen. It can be found in aerobic and anaerobic organisms. Phosphorylation traps glucose with the help of the enzyme hexokinase.
