Q13 / 120 · NEET 2011 (Mains) · Botany

The figure below shows the structure of a mitochondrion with its four parts labelled (A), (B), (C) and (D). Select the part correctly matched with its function. Figure

  • A
    D-Outer membrane-gives-rise to inner membrane by splitting
  • Correct answer
    B
    B-Inner membrane-forms infolding called cristae
  • C
    C-Cristae-possess single circular DNA molecule and ribosomes
  • D
    A-Matrix-major site for respiratory chain enzymes

Solution

The inner membrane of mitochondria forms a number of infoldings called the cristae (sing-crista) towards the matrix. The cristae increase the surface area.

Hence, the correct answer is option: 'B'.
