How much ATP does glucose breakdown produce?

The breakdown of glucose through cellular respiration primarily occurs in two stages: glycolysis and the Krebs cycle. In glycolysis, which takes place in the cytoplasm, 2 ATP and 2 NADH are produced. During the Krebs cycle in the mitochondria, additional 2 ATP, 6 NADH, and 2 FADH2 are generated. The entire process yields 32-34 ATP when oxygen is present. In contrast, under anaerobic conditions, fermentation results in only 2 ATP from one glucose molecule. Understanding these pathways is crucial for studying cellular energy production.
