Structure of a mitochondria

Answer 1

A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. The two membranes, however, have different properties. Because of this double-membraned organization, there are five distinct compartments within the mitochondrion. There is the outer mitochondrial membrane, the intermembrane space (the space between the outer and inner membranes), the inner mitochondrial membrane, the cristae space (formed by infoldings of the inner membrane), and the matrix (space within the inner membrane).

Answer 2

A mitochondrion is a double-membraned organelle with an outer membrane and inner membrane. The inner membrane contains folds called cristae that increase its surface area for energy production. Inside the mitochondrion is a fluid-filled space called the matrix where the citric acid cycle and oxidative phosphorylation occur.
