In lecture, we discussed the endosymbiont theory that describes the evolutionary origins of mitochondria and chloroplast. A few scientists think that peroxisomes also have an endosymbiotic evolutionary origin, although most scientists disagree with this hypothesis. Which of the following hypothetical discoveries would provide support for the hypothesis that peroxisomes evolved from bacteria? Discovering that eukaryotic cells cannot live without peroxisomes. All of these hypothetical discoveries would provide support for the hypothesis that peroxisomes have an endosymbiotic evolutionary origin. Identifying the presence of DNA within peroxisomes. Determining that the majority of proteins in peroxisomes have eukaryotic origin.

What types of biological abilities can be combined to create more capable, more complex cells? How does the presecence of different types of ribosomes inside a eukaryotic cell strengthen the endosymbiotic theory? How does chloroplasts and mitochondria found within a cell have two membranes? How does the emergence of endosymbotic theory change the way humans view microorganisms? Will people be comfortable imaginning that the life functions of pants and animals, including their own, are actually dependent on the coexistence of many different microscopic pieces?
The fossil record suggests that the first cells were prokaryotes; scientists believe that eukaryotic cells evolved from prokaryotic cells in a particular manner; this theory is called endosymbiotic theory. Explain,in your own words what is meant by the endosymbiotic theory How does the structure of mitochondria and chloroplasts support the endosymbiotic theory ? asap please.
An endosymbiont is any organism that lives within the body or cells of another organism. Each would have performed mutually benefiting functions from their symbirie relationship. Why are the mitochondria considered an endosybiont in an eukaryotic cell ? They have two membranes have DNA sequences that indicate origin from the alpha- prroteobacteria has a means for using oxygen and create ATP can break down glucose for energy O They contain hydrolytic enzymes
Tell me three characteristics of mitochondria that support the endosymbiotic theory
Which of the following are lines of evidence for endosymbiosis? Inner membranes are similar to plasma membranes of prokaryotes O DNA structure in chloroplasts and mitochondria are similar to that of prokaryotes Mitochondrial ribosomes are more similar to prokaryotic than eukaryotic ribosomes O The DNA found in the nucleus of a eukaryotic cell is very similar to that of prokaryotes.
Which of the following pieces of evidence could support the endosymbiotic theory if found to be true? Traces of peptidoglycan in the cytoplasm in eukaryotes Presence of rRNA in eukaryotes Presence of 80S ribosomes in eukaryotes The discovery of a unicellular eukaryote
According to the endosymbiotic theory, protoeukaryotes did not have ribosomes until the endosymbiosis with mitochondria was established.
Which of the following correctly describes the theory of endosymbiosis. Question 9 options: Mitochondria evolved from a genetic mutation within an ancestral prokaryote. An ancestral prokaryote engulfed another prokaryote that eventually evolved into the organelles we recognize as mitochondria and chloroplasts. Some species of prokaryotes can pick up plasmids left behind by other prokaryotes.
Peroxisomes, unlike mitochondria or chloroplasts, scarcely resemble free-living organisms, yet biologists have suggested that peroxisomes may also have arisen via endosymbiosis. Assuming peroxisomes evolved from ingested bacteria, choose the features mitochondria retain but peroxisomes apparently lost over hundreds of millions of years: Select all that apply. RNA synthesis oxidation of fatty acids DNA replication protein synthesis replication by division inner and outer membranes ATP synthesis
What is the endosymbiotic hypothesis about the origin of mitochondria? What are the molecular facts that support the hypothesis? To which other cellular organelles can the hypothesis also be applied?
The endosymbiont theory states that mitochondria andchloroplasts evolved from symbiotic relationshipsestablished between bacteria-like cells and theprecursors of eukaryotic cells that engulfed them on what basis
Mitochondria and Earth’s higher concentration of atmospheric oxygen allowed early eukaryotes to evolve in size and complexity – to become larger and do more cellular work. Using your understanding of cellular respiration and the role of oxygen in the electron transport chain, discuss how endosymbiosis, and the evolution of mitochondria, was a critical factor in affecting cell size and how much work, i.e., metabolism, the cell can perform.
