Which of the following is true of aerobic respiration compared to anaerobic respiration?
a. aerobic respiration and anaerobic respiration both require oxygen as a final electron acceptor.
b. aerobic respiration uses oxygen as a final electron acceptor, whereas anaerobic respiration uses pyruvate.
c. aerobic respiration is less efficient than all forms of anaerobic respiration, producing less atp and larger end-products.
d. aerobic respiration uses oxygen as a final electron acceptor, whereas anaerobic respiration uses an inorganic molecule other than oxygen as the final electron acceptor.
