Solar energy can energize electrons that move down an electron transport chain. When these electrons move down the chain, the energy is released and is used to make chemical bonds in molecules. The bond can be broken to release the energy. So when energy is needed, the energy stored in the chemical bonds can be released by breaking the bond.
True / False.

Answer:

The given statement is false because there is no involvement of solar energy during electron transport chain.

Explanation:

Solar energy is utilized in photosynthesis but not in electron transport chain(ETC).During ETC electrons are liberated from the reducing equivalent such as NADH,FADH2.The liberated electron moves from one electron carrier to another until it(electron) reaches the terminal electron acceptor oxygen.

        The movement of electrons occur simultaneously with the movement of proton(H+) resulting in the generation of proton motive force(PMF). This proton motive force  helps in the phosphorylation of ADP to form ATP with the reduction of o2 to water.
