The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the components of cytochrome A and cytochrome A3. We need to identify which complex in the electron transport chain (ETC) these cytochromes belong to. 2. **Electron Transport Chain Overview**: The electron transport chain consists of four main complexes (Complex I, II, III, and IV) and is responsible for the production of ATP through oxidative phosphorylation. 3. **Identifying Complexes**: - **Complex I**: Composed of NADH, which is oxidized to NAD+. It facilitates the transfer of electrons and protons from NADH to the chain. - **Complex II**: Composed of FADH2, which is oxidized to FAD. It also contributes electrons to the chain. - **Complex III**: Contains cytochrome b and cytochrome c, facilitating further electron transfer. - **Complex IV**: This is where cytochrome A and cytochrome A3 are located. It is the final complex in the electron transport chain. 4. **Conclusion**: Since cytochrome A and cytochrome A3 are specifically mentioned, they are components of **Complex IV** in the electron transport chain. 5. **Final Answer**: Cytochrome A and cytochrome A3 are the components of **Complex IV**.
