Insulin is synthesized in significant quantities only in beta cells in the pancreas. when the beta cell is appropriately stimulated by rising blood glucose levels, insulin is secreted from the cell by exocytosis. what organelle would be responsible for the packaging and transporting the insulin out of the cell?

Golgi Apparatus

Explanation:

Also called the Golgi Complex (and Golgi Apparatus or Apparatus), this organelle resembles a stack of flat sacks (cisterns). It is usually located in the central region of the cell, near the endoplasmic reticulum. This allows both organelles to perform their functions together in the synthesis and export of substances.

The Golgiense Complex is a membranous organelle (has a simple membrane that delimits its volume) composed of stacked cisterns associated with the Smooth and Rough Endoplasmic Reticulum.

It is responsible for sending synthesized substances inside the cell to the extracellular area, in a process known as Cell Secretion (exocytosis).

It also performs the function of distributing, packaging and modifying proteins. An example of this is the addition of sugars, a process called glycosylation.

The Golgiense Complex also forms the sperm acrosome, the lysosomes, and also aids in the maintenance of the plasma membrane and cell wall.
