As blood passes by active muscle, the percent saturation of hemoglobin is generally (more)?

As blood passes by active muscle, the percent saturation of hemoglobin is generally _______________ because ____________________. A) high; hemoglobin has released all of its oxygen to the muscle for generation of needed ATP via the Citric Acid Cycle. B) low; hemoglobin has released all of its oxygen to the muscle for generation of needed ATP via the Citric Acid Cycle. C) high; hemoglobin has released all of its oxygen to the muscle for generation of needed ATP via the Electron Transport Chain. D) low; hemoglobin has released all of its oxygen to the muscle for generation of needed ATP via the Electron Transport Chain.

1. im sure that the saturation is low, and im 85% sure that the answer is : B) low; hemoglobin has released all of its oxygen to the muscle for generation of needed ATP via the Citric Acid Cycle.
2. D. In the synthesis of ATP, Oxygen is used as the final electron acceptor at the end of the electron transport chain. The citric acid cycle doesn't use any oxygen.
