Question

which stage of cellular respiration in the presence of oxygen produces ATP and NADH and releases CO2?

Answer 1

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.
