Cellular respiration

Cellular respiration is the process by which cells convert glucose and oxygen into energy in the form of adenosine triphosphate (ATP). It occurs in the mitochondria of eukaryotic cells and is essential for the functioning of the cell.
There are three main stages of cellular respiration: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation.
Glycolysis occurs in the cytoplasm and involves breaking down glucose into two molecules of pyruvate. This process does not require oxygen and produces a small amount of ATP and NADH.
The citric acid cycle takes place in the mitochondria and involves further breaking down pyruvate into carbon dioxide. It generates more ATP, NADH, and FADH2.
Finally, oxidative phosphorylation occurs in the inner mitochondrial membrane and is where most of the ATP is produced. NADH and FADH2 from the previous stages donate electrons to the electron transport chain. As electrons move down the chain, protons are pumped across the membrane, creating a proton gradient. ATP synthase then uses this gradient to produce ATP.
Overall, cellular respiration is an essential process for all living organisms as it provides the energy needed for various cellular activities. Without cellular respiration, cells would not be able to function properly, and organisms would not be able to survive.
