The Origin of the Mitochondria Is Best Described by

The endosymbiotic theory describes how mitochondria and chloroplasts cell organelles came to exist in eukaryotic organisms. WHICH sentence in the paragraph provides the strongest evidence for the endosymbiotic theory of the origin of eukaryotes.

The place where ATP is synthesized.

. Presence of organelles such as mitochondria and chloroplasts. Which phrase best describes the function of mitochondria. The origin of mitochondria was preceded by an ATP-consuming compartment the pre-mitochondrion presumably surrounded by one membrane he is not explicit on this point that became converted into the mitochondrion via retargeting of its proteins into a Rickettsia-like α-proteobacterial endosymbiont figure 2 p.

Present in green plants and green algae. In the given situation the birds are receiving food in the form of ticks and the rhinoceros are receiving protection against the. Best describes the function of mitochondria.

Algebra Chemistry Biology World History English Language Arts Psychology Computer Science Economics. C The plasma membrane folds in surrounds the DNA and forms the endoplasmic reticulum. B Mitochondria are involved in energy generation and are present in almost all eukaryotic cells.

C Mitochondria are thought to have evolved from free-living bacteria that were incorporated into. Before mitochondria and chloroplasts were organelles in a cell they were free prokaryotic cells that were absorbed by eukaryotic cells. Lehninger 1964 classified the various theories of possible routes of mitochondrial genesis into three main groups.

Mutualism is a symbiotic relationship in which both interacting species receives the benefit for togetherness. Protists were the first eukaryotes. The endosymbiotic theory explains the evolution of mitochondria and chloroplasts.

The best evidence for the single origin of mitochondria comes from a conserved set of clearly homologous and commonly inherited genes preserved in the mitochondrial DNA across all known eukaryotic. Much evidence supports the conclusion that the mitochondrial genome originated from within the eubacterial 8910 not the archaeal domain of lifeSpecifically among extant bacterial phyla the α-proteobacteria are the closest identified relatives of mitochondria as indicated for example by phylogenetic analyses of both protein-coding genes 89 and. Growth and division of pre-existing mitochondria.

Mitochondria have several of the proteins necessary for photosynthesis. The endosymbiotic hypothesis for the origin of mitochondria and chloroplasts suggests that mitochondria are descended from specialized bacteria probably purple nonsulfur bacteria that somehow survived endocytosis by another species of prokaryote or some other cell type and became incorporated into the cytoplasm. These data confirm that the mitochondrial genome originated from a eubacterial specifically α-proteobacterial ancestor but raise questions about the evolutionary antecedents of the mitochondrial proteome.

The paragraph describes mitochondria and chloroplasts. A Mitochondria and chloroplasts are organelles of eukaryotic cells. Present in cells of all types of aerobic organisms such as plants and animals.

An aerobic bacterium is engulfed but not digested and then evolves into the mitochondrion. Presence of a nucleus. Converts energy for cell use.

The battery or the powerhouse of the cell. Our understanding of the process whereby mitochondria are produced is still very incomplete. Formation from other membranous structures in the cell.

Larger and much more complex than a mitochondrion it is the site where photosynthesis takes place. Presence of a cytoskeleton. B An aerobic bacterium engulfed and digested an anaerobic bacterium then integrated selected genes into its genome.

Known as the powerhouse of the cell it is responsible for energy metabolism and cellular respiration. Complete sequences of numerous mitochondrial many prokaryotic and several nuclear genomes are now available.
