Feliz [49]

The LYSOSOME contains the largest concentration of digestive enzymes. This organelle has an internal acidic pH required for these enzymes to carry out their functions.

The lysosome is a eukaryotic membrane-bound organelle that contains different types of hydrolytic enzymes to degrade cellular components.

This organelle (lysosome) is part of the endomembrane system, which also includes the endoplasmic reticulum, Golgi apparatus, transport vesicles and nuclear envelope.

The main functions of the lysosomal enzymes include degradation and recycling of cellular byproducts, and metabolic roles.
