State the cytochrome b complexes of the mitochondrion

Reference no: EM13175903

The cytochrome b complexes of the mitochondrion and the chloroplast have similar organization and function. They each pass electrons from a reduced quinone to a peripheral membrane protein, pumping protons across the membrane in the process, and contributing to the proton gradient that drives ATP synthesis. In the diagram below identify the components and the membrane orientation of each system by dragging the appropriate labels to their correct positions.
