Electron transport chain Explanation

An electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane. This mechanism is how most plants make their food and it happens in their chloroplasts.
