Final answer:
Option D) Complex IV, listed as cytochrome c reductase complex, is incorrectly named. It should be called cytochrome c oxidase complex. Thus, D is the answer not correctly paired with its name.
Step-by-step explanation:
The respiratory complexes in the question are all part of the electron transport chain, a series of protein complexes located in the inner mitochondrial membrane that play a key role in cellular respiration. The student is asked to identify which of the listed complexes is incorrectly paired with its name.
- Complex I: Known as NADH dehydrogenase complex or NADH-coenzyme Q oxidoreductase.
- Complex II: Recognized as succinate-coenzyme Q oxidoreductase complex or succinate dehydrogenase.
- Complex III: Termed as coenzyme Q-cytochrome c oxidoreductase complex.
- Complex IV: Incorrectly paired here as cytochrome c reductase complex, but accurately known as cytochrome c oxidase complex.
Therefore, option D) complex IV: cytochrome c reductase complex is not correctly paired with its name, should be called cytochrome c oxidase complex. The correct answer is D.
