Oxygen is the gas used by eukaryotic cells for cellular respiration. Oxygen is required for the process of oxidative phosphorylation, which is the final stage of cellular respiration where ATP is produced.
The first stage in cellular respiration is known as Glycolysis.
The first stage of cellular respiration is glycolysis, which occurs in the cytoplasm of cells. This process is thought to be the oldest stage of cellular respiration in evolutionary terms because it is a simple and ancient metabolic pathway that can occur without the presence of oxygen.
Cellular respiration produces ATP from the breakdown of glucose. ATP, NADH, and FADH2 are produced in Glycolysis. NADH and ATP are produced in the Krebs cycle. And 32 ATP and water are produced in the Electron Transport Chain. The first stage of respiration, glycolysis, occurs in the cytoplasm. The later stages occur in the mitochondria.
In the second stage of cellular respiration, pyruvate is transported into the mitochondria, where it enters the citric acid cycle (also known as the Krebs cycle). Within the citric acid cycle, pyruvate is further broken down to generate energy in the form of ATP.
Most of the ATP is produced during the electron transport chain stage of cellular respiration. This is where the majority of ATP molecules are generated through oxidative phosphorylation using energy released from the transfer of electrons along the electron transport chain.

The first stage in cellular respiration is known as Glycolysis.
The most important stage of cellular respiration is the electron transport chain, where the majority of ATP is produced. This stage relies on the transfer of electrons from NADH and FADH2 to generate a proton gradient across the inner mitochondrial membrane, driving ATP synthase to produce ATP.
The stage of cellular respiration that produces the least ATP is glycolysis, which occurs in the cytoplasm of the cell. During glycolysis, a net amount of 2 ATP molecules are produced per glucose molecule.

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.

Water is produced during the electron transport chain stage of cellular respiration. It is a byproduct of the electron transport chain when oxygen is the final electron acceptor, leading to the formation of water molecules.
