$(1)$ $Z$ shape is formed when all the carriers are placed in a sequence on a redox potential scale.
$(2)$ The $4e^-$ released are accepted by various electron acceptors and finally enter into $PS-II$ instead of returning to $PS-I.$
$(3)$ In this process both $PS-I$ and $PS-II$ take part
$(4)$ As the electrons released in various ways do not return to their original donors, such an electron transport is called non-cyclic electron transport.
