BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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.

Detailed explanation-2: -Ribosomes are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes.

Detailed explanation-3: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes.

Detailed explanation-4: -Ribosomes are small organelles and are the sites of protein synthesis (or assembly). They are made of ribosomal protein and ribosomal RNA, and are found in both eukaryotic and prokaryotic cells. Mitochondria are called the power plants of the cell, as they are where most of the cell’s energy is produced.
