Summary Introduction
To review:
The endosymbiosis theory for the origin of the mitochondrion and determine the benefit received by endosymbiotic partner from the symbiotic relationship.
Introduction:
According to the endosymbiosis theory, the origin of mitochondria occurs when aerobic bacteria were engulfed by an anaerobic bacterium, and they both shared a symbiotic relationship about 2 million years ago. The engulfed or the ingested bacteria resulted in mitochondria formation.

- Diagram the endosymbiotic theory of the origin of mitochondria and chloroplastsarrow_forwardAccording 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_forwardDefine the endosymbiotic theory.
