The mitochrondria main function is to produce ATP. ATP is the currency of cells, with out this currency cell function slows down, then eventually can cease. Therefore, any disorder that leads to substantial reduction in ATP production cause lethal problem in the CNS, which needs a continuous supply of ATP. Cyanide poison works this way. it inhibit the electron transport system in the mitichondria, thus resulting death.
Dizziness in mitochondrial disorders can be caused by impaired function in the part of the inner ear that helps maintain balance (vestibular system) or by decreased blood flow to the brain due to poor mitochondrial function. Mitochondria provide energy to cells, including those in the inner ear and brain, so dysfunction can lead to various symptoms, including dizziness.

What pattern of inheritance would lead a geneticist to suspect that an inherited disorder of cell metabolism is due to a defective mitochondrial gene?
A pattern of maternal inheritance, where affected individuals inherit the disorder exclusively from their mother, would suggest a defect in a mitochondrial gene. Mitochondrial genes are inherited from the maternal lineage, as the mitochondria in the egg cell contribute to the offspring's mitochondria. Additionally, a lack of male-to-male transmission and variable expressivity across affected individuals may also point towards a mitochondrial origin of the disorder.
How does the inheritance of mitochondrial DNA different found in the nucleus of cells?
Mitochondrial DNA is only inherited from the mother, while nuclear DNA is inherited from both parents. Mitochondrial DNA is circular and does not undergo recombination, whereas nuclear DNA is linear and can recombine during meiosis. Mitochondrial DNA codes for a small number of genes related to energy production, while nuclear DNA contains genes that determine various traits and characteristics.
Which cell populations would be most affected by mitochondrial cytopathies?
Cells with high energy demands such as muscle cells, nerve cells, and cells in the heart would be most affected by mitochondrial cytopathies, as they rely heavily on mitochondrial function to generate energy in the form of ATP. Dysfunction in mitochondria would lead to impaired energy production, causing symptoms related to these tissues.
What do you think researchers discovered in the mitochondrial DNA taken from the heart cells of older adults?
Researchers discovered that the mitochondrial DNA taken from heart cells of older adults showed more mutations and damage compared to younger individuals. This suggests that mitochondrial function deteriorates with age, which may contribute to age-related heart conditions.
What does mitochondrial DNA code for?
Mitochondrial DNA codes for certain proteins that are essential for the function of the mitochondria, the cell's powerhouse. It also contains genes involved in energy production through oxidative phosphorylation. Mitochondrial DNA is separate from the nuclear DNA and is passed down maternally.
How is dizziness categorized?
As a disorder, dizziness is classified into three categories-vertigo, syncope, and nonsyncope nonverti
How was the identification of nDNA mutations that cause mitochondrial myopathies first made?
first made when a nuclear gene involved in mtDNA replication was found to be defective in a disorder involving a patient with a mitochondrial myopathy
Which diseases can be considered a mitochondrial disorder?
Diseases such as Diabetes mellitus and deafness (DAD), Leber's hereditary optic neuropathy (LHON), Leigh syndrome, and Myoneurogenic gastrointestinal encephalopathy (MNGIE) can be considered to be mitochondrial disorders.

Additionally, a lack of male-to-male transmission and variable expressivity across affected individuals may also point towards a mitochondrial origin of the disorder.
What sort of symptoms might someone with a mitochondrial disorder have?
low energy and fatigue because mitochondria make ATP the bodies energy
What two activities are MOST related to mitochondrial activity?
Is this from Zingylearning? :) If it is, the answer is eating and inhaling oxygen.
What disorder has dizziness a fluctuating hearing loss in one ear and ringing of the ears?
Meniere's disease
What disorder is related to OCD?
Anorexia
Can hearing loss and anemia and dizziness be related?
i dont know thats why i am asking you

Can hyperthyroidism cause dizziness?
Yes, I have this disorder and I hate eating breakfast but not eating enough nutrients accelerates the fatigue and weakness and these triggers diziness.
What is manieres disease?
You mean Menieres Disease, its an inner ear disorder that causes vertigo, disequilibrium, tinnitus, dizziness, and nausea. I unfortunately have Menieres..
