C
Archaea
D
Viruses
검증된 단계별 안내1
Understand the endosymbiotic theory: This theory suggests that certain organelles in eukaryotic cells, such as mitochondria, originated from free-living prokaryotes that were engulfed by ancestral eukaryotic cells.
Identify the characteristics of mitochondria: Mitochondria are known for their role in aerobic respiration, which involves using oxygen to produce ATP, the energy currency of the cell.
Consider the evolutionary relationship: According to the endosymbiotic theory, mitochondria are thought to have evolved from aerobic bacteria because these bacteria are capable of aerobic respiration, similar to mitochondria.
Evaluate the other options: Photosynthetic algae, archaea, and viruses do not fit the characteristics of mitochondria. Photosynthetic algae are eukaryotic and perform photosynthesis, archaea are a distinct group of prokaryotes, and viruses are not capable of independent metabolism.
Conclude the reasoning: Based on the ability to perform aerobic respiration, aerobic bacteria are the most likely ancestors of mitochondria according to the endosymbiotic theory.
