Question

In the current model of the golgi, what forms the Cis golgi?

Answer 1

The cis Golgi is formed by the receiving side of the Golgi apparatus. Transport vesicles from the ER fuse with the cis face and empty their contents into the lumen of the Golgi apparatus. Proteins and lipids undergo modifications and are tagged to be routed to their destinations.

Step-by-step explanation:

The cis Golgi is formed by the receiving side of the Golgi apparatus. As transport vesicles from the endoplasmic reticulum (ER) fuse with the cis face, they empty their contents into the lumen of the Golgi apparatus. Proteins and lipids then travel through the Golgi and undergo further modifications, such as adding short chains of sugar molecules. These modified proteins and lipids are tagged with small molecules to be routed to their proper destinations.

Answer 2

The cis face of the Golgi apparatus receives proteins and lipids from the ER, and it processes and modifies these molecules before they are sent to their cellular destinations.

Step-by-step explanation:

The cis face of the Golgi apparatus is the entry point for proteins and lipids that arrive from the endoplasmic reticulum (ER) in transport vesicles. These vesicles fuse with the cis face, depositing their contents into the Golgi for processing and modification. As substances move through the various compartments of the Golgi, they are modified through the addition of sugar molecules in a process known as glycosylation. The Golgi is equipped with different enzymes in each compartment to facilitate these modifications, and the final products are tagged with molecular markers like phosphate groups that signal their destination within or outside of the cell, such as lysosomes or the plasma membrane.
