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

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.

Questions Asked in NEET exam
- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

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 After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm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