What modifies and packages proteins for export out of the cell?

What modifies and packages proteins for export out of the cell?

The Golgi apparatus or Golgi complex is a flattened, layered, sac-like organelle that looks like a stack of pancakes. The Golgi body modifies & packages proteins and carbohydrates into membrane-bound vesicles for “export” from the cell.

Which structure in the cell modifies sorts and packages?

The Golgi apparatus
The Golgi apparatus modifies, sorts, and packs the proteins into sacs called vesicles. The vesicles fuse with the cell’s plasma membrane. There the vesicles release the proteins, which move through the plasma membrane to the environment outside the cell.

What cell structure packages proteins for export?

Figure 1: The Golgi apparatus modifies and sorts proteins for transport throughout the cell. The Golgi apparatus is often found in close proximity to the ER in cells.

Which structure modifies sorts and packages proteins?

The Golgi apparatus modifies, sorts, and packages proteins and other materials from the ER for storage in the cell or release outside the cell. From the Golgi apparatus, proteins are “shipped” to their final destination inside or outside the cell. Plants and some other organisms contain chloroplasts.

Which organelle packages proteins?

The organelle that modifies and packages proteins is the Golgi apparatus. This organelle comprises several flattened sacs called cisternae. The Golgi apparatus, also called the Golgi body or Golgi complex, has two sides or faces, the cis face and the trans face, as described in “The Cell: A Molecular Approach.”.

How does the Golgi apparatus retrieve a protein?

The Golgi apparatus retrieves proteins carried in vesicles made in the endoplasmic reticulum. The organelle then modifies these proteins by chopping off some sections or adding necessary molecules. A vesicle then forms around the protein, pinches off of the Golgi apparatus and travels to where the protein is needed.

Where does a vesicle form around a protein?

A vesicle then forms around the protein, pinches off of the Golgi apparatus and travels to where the protein is needed. The cis face of the Golgi apparatus lies near the endoplasmic reticulum to receive its products.
