A schematic diagram of the helical structure of cytochrome b562 is reproduced below. This protein belongs to the family of -proteins that have a four-helix bundle. Number the helices 1 – 4 according to their N  C direction. Indicate relative orientations of the macrodipoles of helices 1 – 4 adjacent to the diagram of cytochrome b562. Remember that according to the definition of a dipole that the arrow points towards the positive end.
