It frees up NADH to be used in glycolysis again.
Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.
the two main types of cellular respiration are aerobic cellular respiration and anaerobic cellular respiration.
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
Citric acid is formed during the citric acid (Krebs) cycle, which is the second stage of cellular respiration. In this cycle, acetyl-CoA is oxidized to produce ATP, CO2, and NADH in a series of reactions that take place in the mitochondria.
The first stage of cellular respiration, glycolysis, takes place in the cytoplasm of the cell.
actually there are two types of cellular respiration:aerobic and anaerobic. aerobic cellular respiration only takes place when there is a presence of oxygen, while anaerobic or also called as fermentation takes place even w/out oxygen.

The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.

The second main part of cellular respiration is the Krebs cycle, also known as the citric acid cycle. This cycle takes place in the mitochondria of cells and involves a series of chemical reactions that ultimately result in the production of ATP, carbon dioxide, and high-energy electrons.
Ya, it is the second stage in respiration.
In the Mitochondria
Carbon dioxide

the process of calvin cycle is the second stage of cellular respiration
If oxygen is not available during the second stage: the glucose (now pyruvate molecule, after glycolysis) the pyruvate can not enter the mitochondrial membrane so it takes an alternative method of producing ATP Other organisms can continue 'cellular respiration' with out the need of O2 (anaerobic method) such as: •Yeast i) Alcohol fermentation •Human Muscle cells i) Produces lactic acid, which makes your muscles sore
