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?
Under 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.
The endosymbiotic theory pertains to which organelle within eukaryotes because of
the presence of 70S ribosomes, circular DNA, and the replication of this organelle
independent from mitosis?
O 1) nucleus
O 2) lysosomes.
O 3) golgi
4) endoplasmic reticulum

- 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).arrow_forward1) Discuss several characteristics of mitochondria and chloroplasts that lend evidence to the endosymbiotic theory.
