Oxidative phosphorylation is carried out by electron transport chain (ETC) present in the mitochondria of aerobes. The NADH or FADH2 produced in TCA (Kreb's) cycle transfers their electron to the ETC to finally reduce O ₂ . Based on this information, the correct option is

Options

  1. AComplex I of ETC is also an enzyme of the TCA cycle.
  2. BComplex I transfers electrons to complex II in the ETC.
  3. CComplex IV is an ATP synthase.
  4. DComplex II does not transfer protons into the inter-membrane space.

Correct answer

D. Complex II does not transfer protons into the inter-membrane space.
