Cristae (singular crista) are the internal compartments formed by the inner membrane of a mitochondrion. They are studded with proteins, including ATP synthase and a variety of cytochromes.


are the infoldings of the inner membrane of a mitochondrion. They are studded with proteins, including ATP synthase and a variety of cytochromes, and function in cellular respiration.

Cristae: These tubular projections of the inner membrane increase the surface area for oxidative phosphorylation.

The inner membrane folds over many times (cristae). That folding increases the surface area inside the organelle. Many of the chemical reactions happen on the inner membrane of the mitochondria.

The inner membrane is folded inwards to form projections called . Inside this is the matrix.
Most of the reactions for aerobic respiration take place in the mitochondria so it is an incredibly important organelle.

Similarly, the inner membrane, which is highly convoluted so that a large number of infoldings called cristae are formed, also allows only certain molecules to pass through it and is much more selective than the outer membrane.

The folding of the increases its surface area, providing space for thousands of copies of the chain in each mitochondrion.
Most components of the chain are proteins bound to prosthetic groups, nonprotein components essential for catalysis.

The mitochondria have an outer membrane and an inner membrane that is thrown into folds called cristae. The mitochondria contains the enzymes that carry out the Krebs Cycle, the metabolic pathway involved in the oxidation of the food we eat.

Whereas Kreb's Cycle occurs in the matrix of the mitochondrion, the Electron Transport System (ETS) chemicals are embedded in the membranes known as the .

A mitochondrion consists of outer and inner membranes, an intermembrane space (space in between the membranes), the cristae (infoldings of the inner membrane), and the matrix (space within the inner membrane).

They have mitochondria with tubular rather than the flattened typical of most mitochondria.

But the inner membrane is highly convoluted, forming folds (cristae) as seen in the cross-section, above. The cristae greatly increase the inner membrane's surface area.
