True or False: Glycolysis, the citric acid cycle, and the electron transport chain are three individual reactions that independently produce ATP. Justify your answer.

• A. True. Glycolysis, the citric acid cycle, and the electron transport chain are three individual reactions that independently synthesize ATP.
• B. False. The pyruvate produced in glycolysis is converted to acetyl-CoA, which enters the citric acid cycle, making the two processes connected but not the electron transport chain.
• C. False. The NADH and FADH₂ produced in glycolysis and the citric acid cycle enter the electron transport and facilitate the generation of energy needed for ATP synthesis.
• D. False. The GTP generated in the citric acid cycle is the energy used for ATP synthesis in the electron transport chain making the two processes connected.
