Mitochondria are called power house of cell, as the food material is gradually oxidised and energy generated is stored in the form of ATP. The enzymes for Krebs cycle (aerobic respiration) and fatty acid oxidation are found in matrix of mitochondria.
A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
