Package of enzymes bounded by membrane is called?

Cells contain various organelles, each with specialized functions. The question asks for a membrane-bound package of enzymes. While lysosomes are the classic example of membrane-bound sacs containing digestive enzymes, they are formed by another organelle.

• The Golgi apparatus is the correct answer. It is a vital organelle responsible for modifying, sorting, and packaging proteins and lipids into vesicles for secretion or delivery to other organelles. This packaging process includes enzymes. For instance, lysosomes, which are membrane-bound sacs containing digestive enzymes, are formed from vesicles budding off the Golgi apparatus.
• Ribosomes are responsible for protein synthesis but are not membrane-bound packages of enzymes.
• The Endoplasmic reticulum is involved in protein and lipid synthesis and transport, but not primarily as a package of enzymes.
• Cytoplasm is the jelly-like substance filling the cell, not a specific membrane-bound organelle.

Thus, the Golgi apparatus is intricately involved in creating and packaging these enzyme-filled, membrane-bound structures.
