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 molecules
- The 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.
