Lysosomes: important function in the process of intracellular digestion (magnified image of a lysosome under a microscope)
What they are - definition
Lysosomes are organelles present in the cytoplasm of the vast majority of eukaryotic cells. Inside the lysosomes we can find a lot of digestive enzymes.
Where are they formed
Lysosomes are formed in the Golgi Complex (another important organelle present in the cytoplasm).
- Degradation and digestion of particles originating from the environment outside the cells;
- Recycle (cell renewal function) other cell organelles that are aged. This process is known as autophagy.
Lysosome Digestive Enzymes
Digestive enzymes present in large quantities within the lysosomes originate in the rough endoplasmic reticulum (another organelle present in the cytoplasm).
