WebApr 10, 2024 · Now, the lysosome is a specific type of organelle that's very acidic. So that means that it has to be protected from the rest of the inside of the cell. It's a compartment, then, that has a membrane around it that stores the digestive enzymes that require this acid, low-pH environment. 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. In some cells they"re essential for lipid break down. They help liver cells detoxify chemicals and drugs.
