Which structures perform the function of mi tochondria in bacteria?
Correct answer: D. Mesosomes
- A. Nucleoid
- B. Ribosomes
- C. Cell wall
- D. Mesosomes
Explanation
Mesosomes are specialized structures in bacteria that function similarly to mitochondria in eukaryotic cells. They are formed by invaginations of the plasma membrane and contain enzymes involved in cellular respiration, thus playing a crucial role in energy metabolism.In contrast, the other options do not serve this function: the nucleoid is simply the region of genetic material; ribosomes are involved in protein synthesis; and the cell wall provides protection and shape but does not participate in energy production. Therefore, mesosomes are the correct answer as they fulfill a role akin to that of mitochondria.
