Document Summary
Eukaryotic cells have mitochondria: most eukaryotic cells contain mitochondria, but not all, mammalian red blood cells do not, some single-celled protists. Giardia lamblia: modified mitochondria; no atp production. Monocercomonoides: found in chinchilla gut, no mitochondria. Basis for endosymbiotic theory: evolutionary theory to explain eukaryotic cells. History of endosymbiont theory: konstantin mereschowski, 1910 (cid:862)the theory of two plasms as the basis of symbiogenesis, a new study or the. Organization and distribution: numbers and locations of mitochondria differ, cell type (ex. epithelial cells vs myocytes, cell needs (energy, organization, associated with cytoskeleton, not always individual (cid:862)(cid:271)ea(cid:374)-shaped(cid:863) u(cid:374)its, form networks, dynamic, constantly growing, dividing, rearranging. Inner membrane: act as barrier, separates matrix (space inside mitochondria) from intermembrane space, much less permeable than om, freely permeable only to oxygen, carbon dioxide, and water, lipid bilayer, contains many proteins, enzymes. Electron transport chain (etc) proteins/lipids/enzymes: transporters.
