Which statement regarding mitochondria is true? Group of answer choices Mitochondria are semi-autonomous which means they can move, make proteins, and divide. Mitochondria are used to recharge ADP into ATP. Scientists theorize that mitochondria were once free-living alpha proteobacteria because mitochondria possess two membranes, bacterial genes, and a bacteria-like chromosome. All previous answers None of these answers
Evidence indicating the chloroplasts were originally free-living prokaryotes that subsequently evolved a symbiotic relationship with a eukaryotic host includes all of the following except: Ability of chloroplasts to synthesize all their own proteins Presence of circular DNA in chloroplasts and in free-living prokaryotes Similarities of rRNA sequences between chloroplasts and free-living prokaryotes Similarities of structures between chloroplasts and some contemporary free-living prokaryotes C
Which of the following statements concerning the endosymbiotic theory is FALSE? O The endosymbiotic theory is widely accepted. O Mitochondria and chloroplasts can divide independently of the cell. Mitochondria and chloroplasts have their own DNA and ribosomes. O Eukaryotes were formed from the union of small anaerobic cells by larger aerobic cells.
Which of these do all prokaryotes and eukaryotes share? a. nuclear envelope b. cell walls c. organelles d. plasma membrane
According to the endosymbiotic theory, why did the primitive eukaryotic cell fail to digest the non-photosynthetic prokaryote that later became an energy-producing organelle? Because the engulfed cell provided the host cell with carbon dioxide. Because the host cell was able to survive anaerobic conditions with the engulfed cell alive. Because the engulfed cell allowed the host cell to metabolize glucose. Because the engulfed cell provided the host cell with adenosine triphosphate (ATP).
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
Which of these statements is not true - ?regarding inclusion bodies in prokaryotes Gas vacuoles are found in blue-green bacteria Reserve material is stored in these structures They are bound by a single membrane O They lie free in the cytoplasm O
If endosymbiosis generated mitochondria and chloroplasts from an ancestral proteobacteria and cyanobacteria, respectively, speculate as to why an endosymbiotic event never generated an organelle specifically tasked for cellulose degradation in eukaryotic cells. Strictly no plagiarism.
The image below shows a density gradient centrifugation carried out to separate a mixture of lysosomes, peroxisomes and mitochondria Organelle mixture 60L 1.11 Centrifuge 1.15 2 1.19 1.22 1.25 Which fraction would you take to obtain mitichondria, and why? O Fraction 2 because mitochondria contain haemoglobin. giving them a reddish colour O Fraction 3 because it is the most dense fraction O It is impossible to decide without further testing O Fraction 1 because it is the least dense fraction O Fraction 2, because mitochondria contain haem, giving them a reddish colour Increasing density of sucrose (g/cm³) 3.
Tell me three characteristics of mitochondria that support the endosymbiotic theory
Below are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. Although both prokaryotes and eukaryotes have a plasma membrane that protects them from their surrounding, many of the extremophiles are prokaryotic and only a few are eukaryotic. b. Despite different in appearance, nerve and muscles cell have the same genetic material and the same ability to produce electrochemical impulses. c. Although very few in numbers, there are special prokaryotes that have a membrane-bound nucleus.
Which of the following is NOT a way in which the prokaryotic groups differ from the Eukaryotes? O A Prokaryotes replicate using binary fission, while most Eukaryotes use mitosis. O B Prokaryotes have circular chromosomes, while Eukaryotes do not. O C Prokaryotes have representatives of more metabolic styles than Eukaryotes. D Eukaryotes have thick layers of peptidoglycan, while Prokaryotes do not. O E Eukaryotes have more complex flagella than prokaryotes.
