Question

The cell is comprised of very important components including the mitochondria. Please view this video describing mitochondrial disease which is found here. Keep in mind that one of the symptoms of mitochondrial disease is fatigue (weak and tired). Next discuss two (2) functions of mitochondria and why you believe each of these functions is important. Then explain two (2) ways that the inability of mitochondria to perform their proper function can account for mitochondrial disease symptoms. Justify your response.

Explanation / Answer

**Video???

2 functions of mitochondria,

First, they are the energy factories of the cell. They are responsible for generation of ATP through oxidative phosphorylaiton.

Second, Regulation of cellular metabolism through Kreb's cycle. This cycle is solely responsible for regulation of cellular metabolism.

inability of mitochondria to perform their proper function can be due to :-

It solely depends on the fact that mitochondria of which body part have been effected. For eg: in liver mitochondria help in carrying out urea cycle, so , if mitochondria of liver are affected, urea cycle will be effected. Similarly, mitochondria are also involved for estrogen and testosterone synthesis. So, a mutation in mt of gonadal cells will effect the reproductive ability of a person.
