Answer:

7 B

8 D

Step-by-step explanation:

Oxygen is the final electron acceptor, thus it accepts electrons at the end of electron transport chain (and turns into water when combined with hydrogen).

Molecules such as glucose (which contains carbons) contain energy and are broken down in cellular respiration. This releases Carbon in the form of Carbon Dioxide. We know from our experience that we release Carbon dioxide by exhaling.
