Question

Figure 9.3 
-The parts of the figure labeled with Roman numerals symbolize what concept?

Quizplus · Accepted Answer

The Roman numerals in the figure represent the four protein complexes (I-IV) that make up the electron transport chain in mitochondria. These complexes are multimeric groups of proteins that work together to transport electrons and generate a proton gradient across the inner mitochondrial membrane. Therefore, the best choice is E, which describes these multimeric protein complexes.
