Question

What process provides the electron transport chain with the energy it needs to function

Answer 1

The electrons are created in the Kreb's Cycle and are transferred in NADH and FADH2 to be used in the electron transport chain.

Answer 2

Redox reactions. The electron transport chain (ETC) is a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
