Detailed explanation-1: -Mitochondria are absent in prokaryotic cells and RBC of mammals. Q. Mitochondria are called powerhouses of the cell.
Detailed explanation-2: -So, the correc answer is ‘Stroma’.
Detailed explanation-3: -Mitochondria are found in all body cells, with the exception of a few. There are usually multiple mitochondria found in one cell, depending upon the function of that type of cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.
Detailed explanation-4: -The cytosol is the fluid in which the cell’s organelles are located. No, glycolysis does not takes place in the mitochondria.
Detailed explanation-5: -Mitochondria contain deoxyribonucleic acid (DNA) and ribosomes, protein-producing organelles in the cytoplasm. Within the mitochondria, the DNA directs the ribosomes to produce proteins as enzymes, or biological catalysts, in ATP production.
