- The non-protein component of the transmembrane complex used by the salt-loving archaeobacterium Halobacterium halobium, which uses sunlight to create a proton gradient for ATP synthesis, is called: bacteriochlorophyll chlorophyll bacteriorhodopsin retinal cytochrome cSome scientists claim that prokaryotes like bacteria have membrane bound organelles, like chromatophores, anammoxosomes and magnetosomes. What really is the truth because it is widely known that prokaryotes do not have membrane bound organelles. Are these claims true or merely speculative? If this is true, what is the physiological basis for this?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.
- 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).In prokaryotes that carry out aerobic respiration, the ________ serves the same purpose as the inner mitochondrial membrane and the ________ serves the same purpose as the mitochondrial matrix. A) ribosomes; plasma membrane B) cytoplasm; plasma membrane C) cytoplasm; cell wall D) cytoplasm; nucleoid E) plasma membrane; cytoplasmWhich 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
