Question:
The complex II of mitochondrial electron transport chain is also known as:
The complex II of mitochondrial electron transport chain is also known as:
Show Hint
Complex II, or succinate dehydrogenase, directly links the citric acid cycle to the electron transport chain by transferring electrons from succinate to ubiquinone (Q), bypassing complex I.

- Succinic dehydrogenase
- Cytochrome c oxidase
- NADH dehydrogenase
- Cytochrome bc1

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Complex II of the mitochondrial electron transport chain is also known as succinate dehydrogenase. This enzyme plays a crucial role in the citric acid cycle (Krebs cycle) and the electron transport chain by catalyzing the oxidation of succinate to fumarate, while transferring electrons to the electron transport chain.
Thus, the correct answer is Succinic dehydrogenase.

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]
