MICROANATOMY

Detailed explanation-1: -In the final stage of transport through the Golgi apparatus, modified proteins and lipids are sorted in the trans Golgi network and are packaged into vesicles at the trans face. These vesicles then deliver the molecules to their target destinations, such as lysosomes or the cell membrane.

Detailed explanation-2: -Vesicles are also used as chemical reaction chambers. They can be classified by their contents and function. Transport vesicles are able to move molecules between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus.

Detailed explanation-3: -Proteins and lipids move through the Golgi stack in the cis-to-trans direction. This movement may occur by vesicular transport, by progressive maturation of the cis cisternae that migrate continuously through the stack, or by a combination of these two mechanisms.

Detailed explanation-4: -The vesicular trasnport model posits that the Golgi cisternae are stable compartments that house certain protein modification enzymes that function to add or remove sugars, add sulfate groups, and perform other modifications.
