The image shows the flow of electrons through electron carriers I, II, III, and IV within the mitochondrial inner membrane. The electronegativity of the protein carriers determines their capacity to attract electrons. Based on the image, which of the following best describes the electronegativity of the carriers and the synthesis and utilization of ATP during the electron-transfer process? Electron carrier I is the least electronegative, and electron carrier IV is the most electronegative. ATP is required for electron transfer between carriers. Electron carrier I is the most electronegative, and electron carrier IV is the least electronegative. ATP is not required for electron transfer between carriers.
