Glycolysis, Krebs Cycle And The Electron Transport Chain

The three processes involved in aerobic respiration are Glycolysis, Krebs cycle and the Electron Transport Chain. In cellular respiration when molecules are entered into the cell, when glucose enters a tissue cell. In the cell, cellular respiration will oxidized the glucose molecule which yields in high resulting elections. By this, the storage form in cells will make ATP. Glycolosis, is defined as splitting sugars with is the first step in cellular respiration occur in the cytoplasm of the cell. Two ATP molecules transfer energy to the glucose energy forming a 6 carbon sugar diphosphate, as it splits into a 2, 3 carbon molecules are converted to pyruvate which forms ATP. In the process of this action, a net of 2 molecules of atp, 2 molecules of pyruvate, and 2 electron carrying molecules oh NADH are produce, Although when oxygen is present, pyruvate and NADH enter the mitochondria when yields the next stage of cellular respiration.

A pyruvate molecule of actyl CoA in converted into additional compounds by which the pyruvate oxidation reaction transfers electrons to the NAD that results in the assembly of NADH. This is where a carbon is loss resulting in carbon dioxide. The Krebs cycle, actyl CoA, binds with oxaloacetate, in enzyme redox reactions, carbons, hydrogen’s, oxygen’s in pyruvate end up as carbon dioxide and water. In glycolosis, every glucose that enters the path way of the cycle with complete twice, this occurs one for each of the molcecule of the pyruvate that has entered the mitochondria at this step. During pyruvate oxidation and krebs cycle, a net of 8 NADH, 2 FADH 2 ,2 ATP and 6 Co2 are produce for each glucose
