Unlike other organelles (miniature organs within the cell), mitochondria have two membranes, an outer one and an inner one. Each membrane has different functions. Mitochondria have different ...

In biology classes from high school through university, I learned that mitochondria are little objects that reside within ...

Mitochondria are double membrane bound cytoplasmic organelles ... space’, which is a narrow region between the inner and outer mitochondrial membranes. The second compartment is called the ...

which is mediated by the coordinated activities of mitofusins in the outer mitochondrial membrane and OPA1 in the inner mitochondrial membrane. The mitochondrial matrix contains red or green ...

Mitochondria—the organelles responsible for energy production in human cells—were once free-living organisms that found their way into early eukaryotic cells over a billion years ago.

A 3D reconstruction showing the inner mitochondrial membrane (red) herniating into a closely associated lysosome (green). The outer mitochondrial membrane is shown in blue and the nucleus is shown ...

Individual mitochondria are capsule shaped, with an outer membrane and an undulating inner membrane, which resembles protruding fingers. These membranous pleats are called cristae, and serve to ...

Mitochondria, the so-called "powerhouse ... Every mitochondrion has two layers of membranes: the outer membrane and the inner membrane. On the inner membrane, folds called cristae contain proteins ...

An outer mitochondrial membrane about 60 – 70Å thick containing proteins called porins surrounds a folded inner mitochondrial membrane. The outer membrane incorporates enzymes that contribute ...
