NEET Botany Electron Transport Chain MCQ Question
Which of the following combinations accurately describes components and processes involved in the Electron Transport Chain?
NADH is oxidised by complex I, electrons are transferred to ubiquinone, and oxygen is the final electron acceptor.
FADH2 is oxidised by complex III, electrons are transferred to cytochrome c, and ATP is synthesised directly at this stage.
Electrons from succinate are used in complex I, ubiquinone is reduced to ubiquinol, and water is produced from NADH.
Cytochrome c acts as a mobile carrier between complex II and complex IV, while O2 is reduced to CO2.
Correct Answer
Detailed Explanation
The correct statements from the NCERT context indicate that NADH is oxidised by complex I, electrons are transferred to ubiquinone, and ultimately, oxygen acts as the final electron acceptor, forming water.
