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.
D-Outer membrane-gives-rise to inner membrane by splitting
B-Inner membrane-forms infolding called cristae
C-Cristae-possess single circular DNA molecule and ribosomes
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.
