The three stages of respiration process are Glycolysis, the Krebs cycle and the Elecrtron transport chain

What is Respiration?

Respiration is the biological process through which living organisms obtain energy by converting nutrients into usable energy forms by converting glucose and oxygen into carbon dioxide, water, and energy in the form of adenosine triphosphate

It occurs in three main stages:

(1) Glycolysis, which takes place in the cytoplasm and breaks down glucose into pyruvate

(2) the Krebs cycle, occurring in the mitochondria, which further oxidizes pyruvate, releasing carbon dioxide and transferring energy-rich electrons to carrier molecules

(3) the Electron Transport Chain, where electrons move through protein complexes, generating a flow of protons and ultimately producing ATP. This process is crucial for sustaining life and providing the necessary energy for cellular activities.
