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. A diagram of mitochondrial inner membrane showing electron flow. Electron carrier Upper I is the most electronegative, and electron carrier Upper I Upper V is the least electronegative. A T P is not related to the electron flow. 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. Electron carrier I is the most electronegative, and electron carrier IV is the least electronegative. ATP is utilized in a distinct reaction, not directly coupled with electron transfer. Electron carrier I is the least electronegative, and electron carrier IV is the most electronegative. ATP is synthesized in a distinct reaction, not directly coupled with electron transfer.
