5 0

All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. Unlike bacteria, most viruses do cause disease, and they're quite specific about the cells they attack.

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.
