<prompt> All of the following are true about mitochondria exceptEvolved from aerobic bacteria engulfed by eukaryotic cellsHave role in regulation of apoptosisHave their own genomeMitochondrial diseases are paternal in inheritance  <response>: Over a billion years ago, aerobic bacteria were engulfed by eukaryotic cells and evolved into mitochondria, providing the eukaryotic cells with the ability to form the energy-rich compound ATP by oxidative phosphorylation. Mitochondria perform other functions, including a role in the regulation of apoptosis programmed cell death, but oxidative phosphorylation is the most crucial. Consistent with their origin from aerobic bacteria, the mitochondria have their own genome. As a zygote, mitochondria are derived from the ovum, their inheritance is maternal. This maternal inheritance has been used as a tool to track evolutionary descent. Mitochondria have an ineffective DNA repair system, and the mutation rate for mitochondrial DNA is over 10 times the rate of nuclear DNA.Reference: Ganongs Review of Medical Physiology; 25th edition; Page no: 36
