The stage of cellular respiration that takes place in the presence of oxygen and produces ATP, NADH, and releases CO2 is called the Krebs cycle (also known as the citric acid cycle or tricarboxylic acid cycle). This cycle occurs in the mitochondrial matrix and is a key part of aerobic respiration. In the Krebs cycle, acetyl-CoA is oxidized, and for each turn of the cycle, CO2 is released, NADH and FADH2 (another electron carrier) are generated, and ATP (or GTP) is produced.
which stage of cellular respiration in the presence of oxygen produces ATP and NADH and releases CO2?
