True or False: O2 is a Byproduct of the Krebs Cycle

False. In the Krebs cycle, also known as the citric acid cycle or TCA cycle, oxygen (O2) is not a direct byproduct. The Krebs cycle is involved in the aerobic respiration process where it contributes to the generation of electron carriers like NADH and FADH2. These carriers then participate in the electron transport chain, where oxygen acts as the final electron acceptor. While oxygen is crucial for the overall process of aerobic respiration, it is not produced as a byproduct of the Krebs cycle itself.
