In mitochondrial electron transport system, for every two pairs of electrons that pass from NADH molecules through a sequential series of cytochrome enzymes to molecular oxygen

Options

(a) 3 ATP
(b) 4 ATP
(c) 6 ATP
(d) 2 ATP

Correct Answer:

6 ATP

Explanation:

In mitochondrial electron transport system, a pair of electrons passing from NADH molecules through sequential series of cytochrome enzymes to molecular oxygen, give rise to 3 ATP . So, two pairs of electrons will give 6 ATP.
