On each step in Electron Transport Sustem chain, a small charge is given off that will be used to synthesize ATP in the process of phosphorylation. When the electrons leave the chain, in pris, they combine with oxygen (final acceptor) to form water. During this process water is and why: A) oxidized because electrons are lost which produces oxidized water
B) oxidized because electrons are gained which produces oxidized water
C) reduced because electrons are gained which produces reduced water
D) reduced, because electrons are lost which produces reduced water
