Cellular respiration is a metabolic pathway that is one of the most important reactions that occur in cells and is involved in the break down of glucose and in the production of ATP.
Glycolysis: is the process of breaking down glucose into two molecules of pyruvate.
Therefore, the start product is glucose and the end product is pyruvate.
Bridge Reaction: forms a bridge between the glycolysis and the Kreb cycle.
Therefore, the start product is pyruvate and the end product is acetyl-CoA.
Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria. There, it’s converted into a two-carbon molecule bound to Coenzyme A, known as acetyl CoA. Carbon dioxide is released and NADH is generated.
Kreb Cycle: as it is a cycle, it is a continuous process. It is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins, into adenosine triphosphate (ATP) and carbon dioxide.
The starting or reactant molecules are Acetyl-CoA and oxaloacetate (which combines with oxaloacetate to produce citrate) and the end product is malate which subsequently re-enters the cycle.
Electron transport chain: All of the electrons that enter the transport chain come from NADH and FADH 2, which are produced during earlier stages of cellular respiration: glycolysis, pyruvate oxidation, and the citric acid cycle.
Starting molecules are the electrons that enter the chain and the final or end product is ATP molecule.
