Explanation:
Answer
The correct sequence is given below.
Explanation:
A. NAD+ (It recieves electrons directly from substrate in glycolytic as well as Citric acid cycle reactions)
B. Oxidoreductase (It is present as complex I termed NAD+-CoQ oxidoreductase. It receives electrons from NADH)
C. Quinone (It is present as Ubiquinone in complex III of Electron transport chain. It receives electrons from NADH and FADH2)
D. Terminal oxidase (It is complex IV of electron transport chain termed as Cyt c oxidase)
E. Oxygen (It is the final acceptor of electrons and gets reduced to water)
