Q. The inner membrane of the mitochondria is, usually, highly convoluted forming a series of infoldings known as

AIPMTAIPMT 1994Cell : The Unit of Life

Solution:

The inner membrane of the mitochondria is infolded variously to form involutions called cristae. The cristae extend inward to varying degrees and may fuse with those from the opposite side, dividing the mitochondrion into compartments. The cristae are arranged in characteristic ways in different cells. They may be simple or branched, straight or zigzag, lamellar or tubular. The cristae have in them a narrow intracristal space. It is continuous with the intermembrane space. They greatly increase the inner surface area of the mitochondria to hold a variety of enzymes.
