Which of the following has a vital role in autophagy?
Correct answer: D. Lysosomes
- A. Glyoxysomes
- B. None of these
- C. Golgi apparatus
- D. Lysosomes
Explanation
Autophagy is the self-digestion of damaged organelles in a cell. Lysosomes, also known as ''suicide sacs'', have lytic enzymes in them which when released cause the destruction of unwanted or damaged components in the cell. The glyoxysome is a plant peroxisome, especially found in germinating seeds, involved in the breakdown and conversion of fatty acids to carbohydrates for the nutrition of the seed. The Golgi apparatus works in the packaging from the ER that are further processed and sorted for transport to their eventual destinations(inside the cell, in the membrane, or transported outside).

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
