Textbook Question
Chapter 3, Problem 3AWK
Mitochondria resemble a bacterial cell in a number of ways. Some scientists hypothesize that mitochondria evolved from aerobic prokaryotes that were engulfed by anaerobic eukaryotes, and now both have evolved together in a mutually advantageous way. Can you think of an explanation for why it might have been advantageous for both cells to enter into such an arrangement?

- 1. Why was the great oxygenation event important for mitochondrial development? a) In your own words, define symbiotic. 2. Chloroplasts and mitochondria both contain a circular DNA chromosome, and ribosomes. Why does this evidence support the theory of endosymbiosis as the mechanism for the origin of eukaryotic cells? a) Today, could mitochondria live independently of their eukaryotic cell host? Give two pieces of evidence to support your answer.arrow_forwardHow did the development of Margulis' theory aid in our understanding of how complex organisms came into existencearrow_forwardAccording to the endosymbiotic theory, which of the following is NOT true about the evolution of life on earth? Eukaryotes and prokaryotes appeared at about the same time and evolved independently from each other. O None of the other four answers (all are true statements) Eukaryotes evolved from symbiotic prokaryotes living inside other prokaryotes Mitochondria and chloroplasts are in some ways similar to prokaryotes The first life on earth was simple organisms, similar to today's prokaryotesarrow_forward
- Imagine you are working in a lab and studying three species of yeast, which are eukaryotic organisms. The first species (Species A) of yeast generates ATP using aerobic cellular respiration. The second species of yeast (Species B) generates ATP using alcohol fermentation. The third species of yeast (Species C) generates ATP using lactic acid fermentation. Which of the following statements are true? All of the other answers are true. Only Species A can grow without oxygen. Species B needs to use 15-16 molecules of glucose to generate the same amount of ATP that is made by Species A using one molecule of glucose. Species C produces more carbon dioxide than does Species B.arrow_forwardin 1967, Lynn Margulis developed the endosymbiotic theory. As seen in the diagram below, the endosymbiotic theory describes how over thousands of years, free-living prokaryotes formed living communities inside larger ancestral prokaryotic cells. Today, we identify those early free-living prokaryotes as the mitochondria, chioroplasts, and possibly other organelles. Endesymbietic Theery How did the development of Margulis' theory aid in our understanding of how complex organisms came into existence? A. It provided an explanation as to why prokaryotic cells do not have a nucdeus. B. It provides an explanation as to why bacteria and mitochondria are similar in size. C. It provides an explanation of how life today could have originated from a single cell. D. It provides an explanation of how prokaryotic and eukaryotic cells use oxygen to work.arrow_forward1) Discuss several characteristics of mitochondria and chloroplasts that lend evidence to the endosymbiotic theory. As stated in the text, this theory may explain the origin of these organelles. Can this theory explain the origin of the ER?arrow_forward
- Considering which organelles were created through the endosymbiotic theory, which of the following is NOT something that the host could receive from the engulfing a symbiont? A. the engulfed cell provided the host cell with adenosine triphosphate (ATP) B. the host cell was able to survive anaerobic conditions with the engulfed cell alive C. the engulfed cell provided the host cell with carbon dioxide D. the engulfed cell allowed the host cell to metabolize glucosearrow_forwardThe endosymbiotic hypothesis for the origin of chloroplasts from gram-negative prokaryotes is supported by all of the following lines of evidence except: the presence of enzymes for the light-dependent and the dark reactions of photosynthesis the presence of circular DNA resembling that of photosynthetic eubacteria the presence of mRNA, tRNA, and rRNA similar to that of the cyanobacteria their use of mitosis rather than binary fission during cell division the presence of 70s ribosomes, consisting of 30s and 50s ribosomal subunitsarrow_forwardThe endosymbiont theory states that mitochondria andchloroplasts evolved from symbiotic relationshipsestablished between bacteria-like cells and theprecursors of eukaryotic cells that engulfed them on what basisarrow_forward
- We know that bacteria and archaea are very diverse in their metabolic capabilities, such as the consumption of organic waste and carbon dioxide and the creation of others such as oxygen, alcohol, methane, nitrates, and antibiotics. Amazingly these known capabilities only come form the 1-10% of prokaryotes that have been identified. Scientists hypothesize that at least 90% are undiscovered and have potential metabolic capabilities we could harness to benefit human life. If you were a scientist, what metabolic capability of bacteria would you try to discover to solve a human or environmental problem? Why?arrow_forwardThe amoeba Pelomyxa palustris is a single-celled eukaryote with nomitochondria, but it contains symbiotic bacteria that can live in thepresence of oxygen. How does this observation support theendosymbiont theory?arrow_forwardUnder the endosymbiotic theory for the origin of the eukaryotic cell. The ancestor of mitochondria and chloroplasts original became part of mutualism with a larger host cell. Which of the following best explains this mutualism? A) The mitochondria and chloroplasts provided specialized reproduction as part of the proto-germ line while the larger host cell provided energy for growth and reproduction. B) The mitochondria and chloroplasts provided gene products that could be used by the larger host cell for improved parasitization. C) The mitochondria and chloroplasts provided molecular energy in return for protection by the larger host cell. D) The mitochondria and chloroplasts produce toxins that the larger cell utilized to defend itself from other cells mutually increasing the defense of all those involved.arrow_forward
