Our bodies are composed to cell. Each cell has organelles that does a particular job for the cell. One of these organelles is mitochondria. The mitochondria provide the energy for the cell in the form of Adenosine Triphosphate (ATP). The one of bond between the phosphates are broken to release the energy. The ATP is made during the process called cellular respiration. The process converts monomer to ATP. According to Shaughnessy, mitochondria has other function such as “playing major role in apoptosis, control of cytosolic Ca2+ (calcium ion) levels, lipid homoeostasis, steroid synthesis, generation of Fe-S (iron-sulfur) center, heme synthesis, innate immune response and metabolic cell signaling.
Just like the cell, the mitochondria have different part. The matrix is the gel like fluid similar to the gel-like fluid cytoplasm. Cristae are the folds in the membrane. The

According to the North American Mitochondrial Disease Consortium, mitochondrial disease primarily effects children but recently adult-onset disorder is frequently being recognized. Mitochondria are abundant in nerve, liver, and muscle cell. The neurons for example need proper distribution of mitochondria to satisfy the energy required to maintain an electrical excitability and synaptic transmission. The function of mitochondria in the neurons are need to produce energy, Ca2+ buffering, axonal, and dendritic transport and release and re-uptake of neurotransmitters (Hanu. N.d.). Thus dysfunctional mitochondria can lead to encephalomyopathy or brain and muscle disease. Mutation in the mtDNA are the causes of mitochondria disease. “In the Kearns-Sayre Syndrome (KSS), single, large-scale mtDNA (usually sproaid ) were detected in muscle biopsies, and mitochondrial ultrastructural and cyttochemical abnormalities in the muscle were apparent” ( MT DNA
