Organelle turnover is controlled by: a) Mitochondria b) Lysosomes c) Golgi bodies d) Nucleus

The correct answer is “b” (Lysosomes)


One of the most important functions of lysosomes is “Organelle turnover.” If extra organelles are there in a cell, then these would be useless for the cell; because the cell’s physiology cannot support this many organelles, for e.g. excess of mitochondria, Golgi bodies, ribosomes etc. In such a situation, the lysosomes, engulf these extra, useless organelles. This phenomenon is a part of “autophagy”; and results in “Organelle turnover”, i.e. maintaining the exact number of each and every organelle inside a cell.
