Question

Inner membrane of mitochondrion possesses

• A. $F_0-F_1$ particles
• B. ATP-ase
• C. TCA enzyme
• D. All of the above

Answer 1

The correct option is D All of the above

• The mitochondria is a double-membraned cell organelle, known as the powerhouse of the cell which is present in all eukaryotic cells.
  
• F0 and F1 particles are found in the inner mitochondrial region and are attached to the cristae and help in ATP production and oxidation.
  
• The enzyme ATP synthase is embedded in the inner mitochondrial membrane helps in the synthesis of ATP molecule (energy currency of the cell).
  
• Enzymes of the citric acid cycle such as succinic dehydrogenase and Isocitrate dehydrogenase are present in the inner mitochondrial membrane.
• So, the correct answer is 'All of the above'.
