Which of the following is/are function (s) of lipochondria? (I)Chemical modification of lipids and proteins (II)Detoxification (III)Formation of acrosome (IV)Glycogen synthesis and breakdown (a)I and II are correct (b)I and III are correct (c)II is incorrect and the remaining are correct (d)II and III are incorrect
Hint: Lipochondria is found in all the eukaryotic cells, plants as well as animals. They are membrane-bound organelle present in the cytosol of the cell. It has the primary function to process and package macromolecules, after their synthesis and before they make their way to their destination.
Complete answer: The function of lipochondria is the chemical modification of lipids and proteins and the formation of the acrosome. Lipochondria is the temporary storage vacuoles of lipids in the Golgi apparatus. Various workers have given various names to this complex, like dictyosome, idiosome, lipochondria, Golgi body, Golgi substance, Golgi body, and Golgi complex. The other functions of lipochondria are- -Its main function is the packaging and secretion of proteins. -They also take part in the transport of lipids and the formation of lysosomes. -It receives proteins from the Endoplasmic Reticulum. -It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane, or secretion. -The enzymatic processing occurs near the membrane surface.
Additional Information: The Golgi body comprises 5 to 8 cup-shaped, series of compartments referred to as cisternae. Cisternae may be a flattened, disk-shaped, stacked pouches that structure the Golgi apparatus. A Golgi stack mostly contains 4 to 8 cisternae. However, around 60 cisternae are found in some protists. A mammalian cell contains around 40 to 100 stacks of cisternae. Animal cells mostly carry around 10 to 20 Golgi stacks per cell, which are connected by tubular connections. The Golgi complex is mostly found near the nucleus. So, the correct answer is 'I and III are correct'.
Note: If there was no Golgi apparatus, various substances would not be in a position to be transformed in proper forms for further use. Certain substances, like protein and lipids, are important for the formation of plasma membranes. Therefore the absence of Golgi apparatus will inhibit the formation of new cells during cell division.
