Answer:
The three major steps of cellular respiration are
Glycolysis
The Kerb's cycle
The Electron Transport Chain
Explanation:
Glycolysis: is a metabolic pathway that converts glucose into pyruvate and a hydrogen ion, it's an anaerobic process
The Kreb's cycle : is a series of chemical reaction used by all aerobic organisms in order to release stored energy through the oxidation of acetyl- CoA
The Electron Transport chain : is a series of complexes that transfer electrons from an electron donor to an electron acceptors via redox- reaction
