Detailed explanation-1: -Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation .
Detailed explanation-2: -Glycolysis. Glycolysis is a metabolic pathway that occurs in the cytosol of the cell and splits glucose into two other molecules, called pyruvate. The free energy released in this process is used to form the high-energy compounds ATP AND NADH.
Detailed explanation-3: -The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration .
