Question

What is the role of the Fe-S cluster in Photosystem II?
a.) It accepts only electrons from the preceding PSII component
b.) It accepts electrons and protons from the preceding PSII component
c.) It is responsible for establishing a pH gradient between the matrix and inner mitochondrial
space
d.) both a and b
e.) both a and c
