Answer:
Anaerobic respiration does not proceed to the electron transport chain
Step-by-step explanation:
Aerobic respiration occurs when oxygen is available. When oxygen is available, glycolysis is followed by the Kreb's cycle and then the electron transport chain. The electron transport chain produces the vast majority of ATP during respiration.
The electron transport chain proceeds when there is the presence of oxygen because oxygen acts as the final electron acceptor in the electron transport chain.
When there is no oxygen to act as the final electron acceptor, the cell must undergo anaerobic respiration, which does not involve the electron transport chain, producing much less energy. See the attached diagram for a picture!
