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.
Options
- AD-Outer membrane-gives-rise to inner membrane by splitting
- BB-Inner membrane-forms infolding called cristae
- CC-Cristae-possess single circular DNA molecule and ribosomes
- DA-Matrix-major site for respiratory chain enzymes
Correct answer
B. B-Inner membrane-forms infolding called cristae
Step-by-step 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.
