The mitochondrial DNA is most similar to the genome of Rickettsia prowazekii; both have been described as small, highly derived, and "reduced and tailored to suit its dependent lifestyle " (Gray 1998). ... Generally, there are 2 to 10 copies of the DNA in each mitochondrion and many mitochondia in each cell.
Cellular components' strange shape may indicate a new role for mitochondria in the brain. Summary: New research suggests that mitochondria help neurons grow and make proper connections in the developing brain. The work could open up new lines of inquiry into may be at play when these processes go awry in brain disease.
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
