In the ETS, electrons from FADH_2 enter into which complex?

In the ETS, electrons from FADH2\text{FADH}_2 enter into which complex?

Options

  1. AComplex I
  2. BComplex II
  3. CComplex III
  4. DComplex IV

Correct answer

B. Complex II

Step-by-step solution

In the electron transport system (ETS), electrons from NADH\text{NADH} are oxidized by Complex I (NADH dehydrogenase).

Electrons from FADH2\text{FADH}_2 are oxidized by Complex II (succinate dehydrogenase).

Therefore, electrons from FADH2\text{FADH}_2 enter the ETS through Complex II.

Answer: Complex II
