All cells need energy. The most common form of cellular energy is ATP. Below is ATP. It is the negative phosphate groups that give this molecule energy as it becomes unstable. When the phosphate is transferred to other molecules, those molecules have energy because they become unstable.. Glycolysis. Glycolysis. First set of reactions involved in extracting energy from glucose. Occurs in the cytoplasm. Nearly all organisms from all branches of life undergo glycolysis in a nearly identical manner. C483 Spring 2013. 1. During . glycolysis, isomerization occurs during which of the following reactions? . A) Fructose 1,6-bisphosphate → . dihydroxyacetone. phosphate and glyceraldehyde 3-phosphate. . Glycolysis . is the breakdown or catabolism of a six carbon glucose molecule in a series of enzyme catalyzed reactions to give 2 molecules of pyruvate which is a 3 carbon compound. Glycolysis takes place in all the cells in the cytosol . During the sequential reactions of glycolysis some of the free energy is stored in the form of ATP and NADH. . Adrian .
