pH Homeostasis of Cellular Organelles Physiology

WebLysosomes, the terminal organelles on the endocytic pathway, digest macromolecules and make their components available to the cell as nutrients. Hydrolytic enzymes specific to a wide range of targets reside within the lysosome; these enzymes are activated by the highly acidic pH (between 4.5 and 5.0) in the organelles' interior.

Another function of organelles is to prevent competing enzymatic reactions from interfering with one another.

WebLet"s talk about another membrane-bound organelle that"s pretty similar to lysosomes. They"re known as "Peroxisomes". Peroxisomes are responsible for a variety of metabolic activities.
