Refer to Scenario 3.1. Why did Tony's muscles become fatigued and burn toward the end of the race?
A) Tony was able to go through gluconeogenesis only, which caused tissue damage throughout his body
B) Tony had an oxygen debt, meaning he no longer had oxygen at the end of the electron transport chain. Therefore, he could only go through beta oxidation, which burned up his fat cells and caused the burning sensation.
C) Tony had an oxygen debt, meaning he no longer had oxygen at the end of the electron transport chain to complete the stages of glucose oxidation. Therefore, pyruvate was being converted to lactic acid which caused the burning sensation in his muscles.
D) Tony had used up all of his energy and carbohydrates in his system. Therefore, he was utilizing proteins for energy; since muscle is made out of protein, this made his muscles burn.
E) Tony was burning up so much energy he was producing excess heat, which caused his muscles to start burning.
