    What he said about the spermatic mitochondria being dissolved by the egg... That's not what happens.
    Actually during fertilization only the nucleus of the sperm passes the layers of the egg and enter it. The tail and rest of the part of the sperm gets dissolved in the uterus (or more precisely the ampullary-isthmic junction of the fallopian tube cuz fertilization takes place over here)

    there is often severe muscle wasting in people with cancer.
    one theory is called: Nuclear Meltdown, and it concerns mitochondria degradation.
    Michael Wiggs and his crew made a mouse model with implanted cancer cells and monitored the health of the mouse and many indications for four weeks, which is when the mice would be euthanized so they didn't die from the cancer.
    many of the indicators they monitored did NOT show a steady degradation, but instead would show minor degradation for the first three weeks, and then a LOT of degradation in the fourth week, and the mouse would be near death.
    But, when they monitored mitochondrial function, they noticed it degraded in a stepping stone fashion.
    this indicates that mitochondria show early changes we can investigate to see if we can intervene in the degradation process before severe muscle loss becomes deadly.

      Anthony Lusich the mitochondria is like a piece of history, they are ancestors of current day bacteria that descended from mitochondria that thrived. You cannot remove mitochondria from a cell and expect it to live, they are dependent on the cell for glycolysis in order to produce the energy we harvest.
