Question

Which organelle is essentially a small sac of digestive enzymes that functions in degrading worn-out organelles as well as macromolecules and particles taken into the cell by endocytosis?

A. A lysosome
B. A peroxisome
C. An endosome
D. The endoplasmic reticulum
E. The Golgi apparatus

Answer 1

Lysosomes are small sacs filled with digestive enzymes that break down worn-out organelles, macromolecules, and particles taken in by the cell. They function in autophagy, the digestion of the cell's own structures, as well as the breakdown of foreign material like pathogens.

Step-by-step explanation:

A lysosome is essentially a small sac of digestive enzymes that functions in degrading worn-out organelles as well as macromolecules and particles taken into the cell by endocytosis. Lysosomes contain enzymes that break down and digest unneeded cellular components, such as damaged organelles or foreign material. They are responsible for processes like autophagy and the digestion of pathogens.
