Glycolysis: (Aerobic Respiration Stage 1) and Exploding Sugar Demo

Stage One: Glycolysis

Glycolysis is the first step of extracting energy from glucose. Glycolysis reaction is a 10-reaction biochemical pathway. Location of glycolysis is cytoplasm of the cell because the enzymes required to carry out glycolysis are present in the cytoplasm. They are not bound to any membrane or organelle. In this reaction, two ATP molecules are used up during initial steps. However, at the end of the cycle, four ATP molecules are formed by the substrate-level phosphorylation. Hence, there is a net yield of 2 ATP while catalyzing one glucose molecule by glycolysis.

Additionally, four electrons are captured during the formation of NADH and that can be used in the production of ATP by aerobic respiration. Also, by this reaction, two molecules of pyruvate are formed that still contain most of the energy the original glucose molecule held. This step occurs in both, aerobic as well as anaerobic respiration.
