a rabbit is scurrying away from an approaching hawk which part of cellular
respiration will provide the rabbit with most of the energy it needs to escape

"Electron transport chain" part of cellular respiration will provide the rabbit with most of the energy it needs to escape.

Explanation:

A collection of complexes that transfer electrons from electron donors to the acceptors by redox reactions which shows simultaneously occurrence of both oxidation and reduction reaction, and combined with the movement of protons i.e across the membrane is understood as ETC (electrons transport chain).

It is the component of aerobic respiration which utilises free oxygen in the form of final electron acceptor in the process of glucose catabolism of the electrons which is derived from the intermediate compounds. Water and ATP are the ETC ‘s end products.
