Step by step
Solved in 2 steps
- How can the hypothesis that asserts that chloroplasts as well as mitochondria were primitive prokaryotes that associated in mutualism with primitive anaerobic eukaryotic cells be corroborated?If mitochondria originated as proteobacteria and chloroplasts are descended from cyanobacteria, where does the rest of the eukaryotic cell come from?How do scientists know that mitochondria and chloroplasts were likely once free-living prokaryotes? What theory is explained by this evidence?
- how are mitochondria and chloraplasts similar to prokaryotes?What key aspects of chloroplasts(and mitochondria) are consistent with the theory that they mayhave once been bacteria? List three specific features.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).
- What is the difference between structure and function of Mitochondria and chloroplastIdentify the eukaryotic organelle that contains 2 membranes, a water soluble compartment for Krebs cycle enzymes, and a lipid soluble compartment for electron transport and oxidative phosphorylation. the chloroplast the mitochondrion the lysosome the peroxisome the ribosomeHow does cellular respiration differ in prokaryotes and eukaryotes?1. Eukaryotes perform reactions in mitochondria; prokaryotes use the plasma membrane. 2. Eukaryotes use substrate-level ATP synthesis; prokaryotes use oxidative phosphorylation.3. Eukaryotes do not use oxygen; prokaryotes only use oxygen. 4. Eukaryotes use NAD+/NADH as electron acceptors; prokaryotes use FAD+/FADH2.
- Although both organelles originated as free-living prokaryotes, mitochondria are significantly smaller than chloroplasts. Suggest a reason for this discrepancy.The origin of the photosynthetic eukaryote took place when a engulfed by a later eukaryote with mitochondria. later eukaryote with mitochondria early eukaryote with chitin later prokaryote with chloroplasts early prokaryote with ribosomes wasParamecia live mostly in freshwater and move with the use of structures called cilia. They utilize contractile vacuoles to expel water that enters the cell by osmosis. Euglena are unicellular organisms that use flagella for movement and chloroplasts for photosynthesis. They are found in freshwater and saltwater. Scientists have determined that Paramecia and Euglena are eukaryotes and not prokaryotes because they have
