Trans

Definition

Trans refers to the trans face of the Golgi apparatus, which is the side where vesicles pinch off and transport materials away. It is essential for sorting and shipping proteins and lipids to their final destinations.

5 Must Know Facts For Your Next Test

1. The trans face of the Golgi apparatus is also known as the exit face.
2. It is opposite to the cis face, which receives vesicles from the endoplasmic reticulum.
3. Vesicles leaving the trans face can be directed to various locations such as lysosomes, plasma membrane, or extracellular space.
4. The trans-Golgi network (TGN) is a key area within the trans face involved in protein sorting and packaging.
5. Proper functioning of the trans face is crucial for maintaining cellular organization and function.
