Document Summary

Cells may contain several of there of have a single, large mitochondrion. Has 2 membranes outer membrane & inner membrane (inward projections called cristae. Carry out aerobic respiration of all eukaryotic cells. Glossary: space between inner & outer membrane - proton lled intermembrane compartment, matrix: space enclosed by the inner membrane, cristae: inward projections of inner membrane. Electron transport chain & turbine atpase of inner mbembrae same as plasma membrane of bacteria. Circular dna chromosome mitochondria: smaller than circular dna of bacteria. Ribosomes (small, sensitive to chloramphenicol etc: ribosomes in mitochondria signi cantly smaller than regular ribosomes in the rest of the cell. Divide by binary ssion (ftsz protein: ftsz used in both bacteria and mitochondria for division, bacteria have membrane folds like mitochondria. ** similarity to bacteria starts to suggest that mitochondria is related to a bacteria. Mitochondria originated from symboptoc aerobic bacteria (alpha-purple) Chloroplasts believe\d to be derived from symbiotic, photosynthetic bacteria (cyanobacteria)
