The Body need energy so with the malfunction of the cells that power the Human Body Mitochondria cells MTDNA are not working so the body cannot sustain normal function organs and bodily functions and In nearly every cell in the body, mitochondria are responsible for producing that energy (called ATP). They are like power stations, supplying the energy our cells need to function.
Cells make up tissues and organs in our bodies, for example the heart and liver. If our cells do not have enough energy, the tissues or organs do not work properly, leading to failure In much the same way, if power stations do not produce enough energy there will be areas of blackout, where parts of the country cannot function.
