Mitochondrial matrix contains in it a large number of:
Correct answer: D. Enzymes, coenzymes, organic and inorganic salts and DNA with ribosomes
- A. Enzymes and coenzymes
- B. Organic and inorganic salts
- C. Enzymes, coenzymes, organic and inorganic salts
- D. Enzymes, coenzymes, organic and inorganic salts and DNA with ribosomes
Explanation
Mitochondria are power houses of the cells where two important phases of aerobic respiration are accomplished i.e., Krebs cycle and respiratory electron transport chain. Thus all enzyme, coenzymes and other substances related to these pathways are present in mitochondria. ATPs are synthesized here. However, some extra chromosomal DNA along with ribosomes are also found in mitochondria.

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.
