Document Summary
Come from phagocytosis of aerobic prokaryote: can divide in the cell: mitochondrial fission . Functions: site of aerobic respiration: utilizing o2 to extract energy from macromolecules (primarily glucose_ and converting it to atp. We use 2x 1026 molecules of atp/day. Atp cell energy source energy is released when atp is hydrolyzed to adp. Many mitochondria in: muscle cells, liver cells, fat cells, plant cells and sperm. Stain (left), another photo of tem (left) and sem of purified mitochondria. Outer mitochondrial membrane (oom) y 50% protein: lipid ratio y contain porin proteins large channels y allow very large molecules through. Matrix y gel- like from high protein [] y contains dna and ribosomes, trna y mitochondrial function requires 3,000 proteins y therefore mitochondria function. Protein translocons are also involved in import of proteins in mitochondria. Mitochondria proteins are completely translated on free ribosomes in cytosol.
