Answer:

1. Oxygen is the terminal electron acceptor in aerobic respiration

2. Pyruvate typically serves as the final electron acceptor during fermentation.

Explanation:

Under normal aerobic conditions, the final electron acceptor at the end of the electron transport chain is oxygen. However, fermentation occurs when there is no oxygen available. Therefore, something else must act as the final electron acceptor. In lactic acid fermentation, NADH is the electron carrier that ultimately carries them to pyruvate. Pyruvate is reduced to lactic acid, and thus, acted as the final electron acceptor.
