NEETBotanyRespiration in Plants
An electron transport complex in the inner mitochondrial membrane contains cytochromes a and a₃ , along with two copper centres. Identify the correct complex number and its specific name.
Options
- AComplex III, Cytochrome bc₁ complex
- BComplex IV, Cytochrome bc₁ complex
- CComplex IV, Cytochrome c oxidase
- DComplex III, Cytochrome c oxidase
Correct answer
C. Complex IV, Cytochrome c oxidase
Step-by-step solution
According to NCERT, Complex IV refers to cytochrome c oxidase complex containing cytochromes a and a₃ , and two copper centres. Complex III is the cytochrome bc₁ complex. Therefore, the complex containing cytochromes a and a₃ with two copper centres is Complex IV, which is named Cytochrome c oxidase. Answer: Complex IV, Cytochrome c oxidase
