EVERYDAY SCIENCE

Detailed explanation-1: -Proteins are sorted into the regulated secretory pathway in the trans Golgi network, where they are packaged into specialized secretory vesicles. These secretory vesicles, which are larger than other transport vesicles, store their contents until specific signals direct their fusion with the plasma membrane.

Detailed explanation-2: -The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire.

Detailed explanation-3: -These Golgi stacks contain anywhere from 3 to 20 flattened membrane sacs, which are called cisternae. These Golgi cisternae are usually classified based on what they import and export into the Golgi body, and each contains a different set of processing enzymes.
