Verified step by step guidance1
Understand that the electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions.
Recognize that as electrons are transferred through the chain, they move from a higher to a lower energy level, releasing energy at each step.
Identify that this released energy is used to pump protons (H+) across the mitochondrial membrane, creating a proton gradient.
Note that the movement of protons back across the membrane through ATP synthase drives the synthesis of ATP from ADP and inorganic phosphate.
Remember that carbon dioxide is not typically released during the electron transport chain; it is a byproduct of earlier stages of cellular respiration, such as the citric acid cycle.
