In Leigh syndrome, a severe neurological disorder, mitochondria are often structurally and functionally altered due to mutations in genes critical for mitochondrial energy production. These alterations can lead to impaired oxidative phosphorylation, resulting in decreased ATP production and increased production of reactive oxygen species. Additionally, mitochondrial morphology may be disrupted, showing features like swelling or clustering, which can further compromise cellular energy metabolism and contribute to the disease's neurological symptoms.

What organelle is most likely to be altered in oxidative phosphorylation disorders?

The mitochondria are the organelles most likely to be altered in oxidative phosphorylation disorders. These disorders often affect the electron transport chain within the mitochondria, leading to a decrease in ATP production and overall cellular energy deficiency.


How would a disease that damages the mitochondria most directly affect the functioning of cells?

Mitochondria convert glucose, lipids, and proteins into ATP, which can then be used tocellular work, by oxidizing them. Without them, energy could not be stored in the cells, and the cell would not be able to perform crucial tasks because there would be no fuel with which to conduct work.


Does mosses have a mitochondria?

Mosses belong to Plantae. So it have mitochondria

Which of these cellular organelles have their own DNA?

Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
