Cristae

Biology  Crista  Crop

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. The maximum surface for chemical reactions to occur is within the mitochondria.


Cristae 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. They provide more surface area for cellular respiration to happen.

And it's the cristae where the electron transport system happens. Now the electron transport system is this last step here, so we began with glycolsis breaking apart the glucose forming pyruvate and spitting off some high energy electrons in the form, are being carried on the electron carrier NADH.

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 increased surface area allows the small organelle to do as much work as possible.

The inner membrane is folded inwards to form projections called cristae. 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 interior of the two membranes is called the matrix, the space in between the two membranes is called the intermembrane space and the folds created by the inner membrane are called cristae.

The folding of the cristae 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. These enzymes are in the fluid part of the matrix.

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 cristae rather than the flattened cristae 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. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell.

The inner membrane invaginates to the interior of the organelle forming cristae that delimitate the internal space known as mitochondrial matrix and where mitochondrial DNA (mtDNA), mitochondrial RNA (mt RNA), mitochondrial ribosomes and respiratory enzymes can be found.

Brown adipocytes present a multilocular distribution of triglyceride deposits and contain numerous mitochondria packed with cristae, consistent with their high metabolic activity. White adipocytes, on the contrary, primarily have an energy storage function, and thus mitochondria are scarce.

Mitochondria
Surrounded by a double membrane with a series of folds called cristae. Functions in energy production through metabolism. Contains its own DNA, and is believed to have originated as a captured bacterium.
