What is the function of the Crista in mitochondria?

To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.

What happens when the mitochondria is damaged?

Widespread damage to mitochondria causes cells to die because they can no longer produce enough energy. Indeed, mitochondria themselves unleash the enzymes responsible for cell death.

What happens when your mitochondria are not working correctly?

If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.

What is the benefit of the inner mitochondrial membrane and its Crista in relation to the electron transport chain?

The inner membrane (IM) has many folds, termed cristae, which increase the surface area available for mitochondrial respiration and are the site of electron transport and oxidative phosphorylation (OXPHOS).

What contains the Crista Ampullaris?

The crista ampullaris is the sensory organ of rotation. They are found in the ampullae of each of the semicircular canals of the inner ear, meaning that there are 3 pairs in total. The function of the crista ampullaris is to sense angular acceleration and deceleration.

What would happen to a cell if the mitochondria cristae were damaged?

Mitochondrial cristae are folds of the mitochondrial inner membrane that provide an increase in the surface area. Having more cristae gives the mitochondrion more locations for ATP production to occur. In fact, without them, the mitochondrion would not be able to keep up with the cell’s ATP needs.

What causes mitochondria to malfunction?

Mitochondrial diseases are caused by abnormal genes that lead to flawed proteins or other molecules in the mitochondria. The various subtypes are caused by alterations in different genes, leading to worn-down cells in different parts of the body.

What are the symptoms of mitochondrial myopathy?

The symptoms of mitochondrial myopathies include muscle weakness or exercise intolerance, heart failure or rhythm disturbances, dementia, movement disorders, stroke-like episodes, deafness, blindness, droopy eyelids, limited mobility of the eyes, vomiting, and seizures.

How does the folding of the inner mitochondrial membrane benefit aerobic respiration?

Part of cell respiration happens by transferring molecules across the inner membrane, so by adding folds, a longer piece of membrane can be stuffed inside the mitochondria. This increases the amount of molecules that can be transferred across it. Increasing surface area can be seen in many other parts of the body too.

What sensation does the crista ampullaris recognize?

What sense is associated with the crista ampullaris?

The crista ampullaris is the sensory organ of rotation located in the semicircular canal of the inner ear. The function of the crista ampullaris is to sense angular acceleration and deceleration.
