Ovules in early stages of development in the ovary segment of the fruit fly. In green - mitochondrial organelles that are not active, in yellow-red - active organelles

Bacteria are fueled

Weizmann Institute scientists have revealed an effect of the gut bacteria on the body's systems mediated through the supply of essential compounds for energy production in the mitochondria
