Which of the following is TRUE about the electron transport chain (ETC)?

The following statement is TRUE about electron transport chain

Electrons start out at very high energy and lose energy at each transfer step.

Explanation:

An electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. The electron transport chain is built up of peptides, enzymes, and other moleculesThe electron transport chain consists of a series of redox reactions in which electrons are transferred from a donor molecule to an acceptor molecule. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.The underlying force driving these reactions is the free energy of the reactants and products.
