MICROANATOMY

Detailed explanation-1: -Transport from the Golgi apparatus. Proteins are sorted in the trans Golgi network and transported in vesicles to their final destinations. In the absence of specific targeting signals, proteins are carried to the plasma membrane by constitutive secretion.

Detailed explanation-2: -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.
