Cellular respiration has three main components: glycolysis, Krebs Cycle, and electron transportation chain/chemiosmosis. There is a fourth component, pyruvate decarboxylation, that connects glycolysis and Krebs Cycle.
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
All three of the basic steps INSPIRATION, VENTILATION and PERFUSION although 1/2 of the 2nd phase or VENTILATION process requires no oxygen and it is the expiration of carbon dioxide from the body through the lungs.
The last three stages of cellular respiration occur in the mitochondria. They are the citric acid cycle (Krebs cycle), electron transport chain, and oxidative phosphorylation. These stages involve the production of ATP, the cell's main source of energy.
Cells release several waste products during metabolic processes. Three common wastes include carbon dioxide, which is produced during cellular respiration; urea, a byproduct of protein metabolism; and metabolic acids such as lactic acid, which can accumulate during anaerobic respiration. These wastes must be efficiently removed to maintain cellular health and homeostasis.
The NADH molecule produces of 2 ATPs during the last stage of respiration. Some think that three ATPs are created from the NADH, however, the last stage of respiration is different than ATP and NADH during electron transfers.

Two of three parts of aerobic respiration take place in mitochondria.Kreb cycle and electron transport chain.
The three processes that occur during cell respiration are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain). Glycolysis breaks down glucose into pyruvate, the citric acid cycle further breaks down pyruvate to produce ATP and electron carriers, and oxidative phosphorylation uses these electron carriers to generate most of the ATP through a series of redox reactions.
During the preparation steps in the second stage of aerobic respiration (Krebs cycle), two carbons depart as carbon dioxide in the conversion of pyruvate to acetyl-CoA. In the cycle proper, all six carbons that entered are released as carbon dioxide molecules in the form of three molecules of CO2.

The two steps in aerobic respiration that produce ATP are glycolysis and oxidative phosphorylation. Glycolysis generates a small amount of ATP directly, while oxidative phosphorylation, which occurs in the mitochondria, produces the majority of ATP through the electron transport chain and ATP synthase.
