ANATOMY

Detailed explanation-1: -Mitochondria are surrounded by a double-membrane system, consisting of inner and outer mitochondrial membranes separated by an intermembrane space (Figure 10.1). The inner membrane forms numerous folds (cristae), which extend into the interior (or matrix) of the organelle.

Detailed explanation-2: -Mitochondria is a double layer oval shaped organelle. The outer membrane and infolded inner membrane. The folds in the inner membrane of a mitochondrion are called as cristae.

Detailed explanation-3: -The inner membrane is contained by the smaller outer membrane because it is invaginated or involuted. The internal compartments defined by the infoldings of the inner membrane are called cristae and the space they enclose is the intracristal space.

Detailed explanation-4: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Detailed explanation-5: -Respiratory Chain and ATP Synthase The ATP synthases comprise a very large group of highly conserved enzymes that are found in the bacterial cytoplasmic membranes, the thylakoid membranes of chloroplasts, and the inner membranes of mitochondria.
