7. What are the two reactions that take place during aerobic respiration and where do they occur?

Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen
