Mitochondria have enzymes for all of these processes except:
Correct answer: D. Fermentation
- A. Replication of DNA
- B. Fatty acid metabolism
- C. Krebs cycle
- D. Fermentation
Explanation
Fermentation is a metabolic process that does not occur in the mitochondria. Instead, it takes place in the cytoplasm of cells. Fermentation is an anaerobic process that occurs when oxygen is not available or limited. It involves the partial breakdown of glucose or other organic molecules to produce energy in the form of ATP (adenosine triphosphate) without the involvement of the mitochondria. Common examples of fermentation include lactic acid fermentation and alcoholic fermentation.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
