Document Summary
Have 2 membrane, outer has pores in it. More space better- ribosomes are floating in there, so increase sa so more can. Inner membrane; has folds in it, enzyme is embedded in the membrane. Eukaryotes have 2 membranes ; outer and inner folded. As sa increases, space increases for enzyme therefore a greater production of work energy. Matrix; citric acid cycle where circular dna is floating around. All maternal, only get it from your mom. Dna is circular ; actively code for proteins and enzymes that function within the mitochondria- these enzymes are very important for mitochondrial function. But mitochondria does not only function with it"s genome, also needs genes from the nucleus. Mitochondria is not self sufficient in terms of genetics; it only has it"s own genome because of how it orginated endo symobiosis. Cells without mitochondria cannot use aerobic metabolism to use energy, only glycolysis this is the ancestral prokaryote.
