When is CO2 generated during processes involved in ATP synthesis? During the electron transport system During glycolysis In the final step of oxidative phosphorylation When pyruvic acid enters the Krebs cycle and during the Krebs cycle the final step of the TCA cycle

Answer 1

CO2 is generated during the final step of oxidative phosphorylation. This occurs in the electron transport system when electrons are transferred through the electron carriers and ultimately combine with oxygen to form water. Additionally, CO2 is also produced when pyruvic acid enters the Krebs cycle and during the Krebs cycle itself, which is part of aerobic respiration and occurs in the mitochondria.
