What stores and modifies proteins?
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER.
What modifies and transport proteins?
The Golgi apparatus
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.
What is responsible for modifying proteins?
The Golgi apparatus is a cellular organelle responsible for the modification and trafficking of proteins to other organelles such as the lysosome, the digestive organelle of the cell. This section focuses on how the modifications done in the Golgi help to direct this process.
Which structure packages and modifies proteins for export?
Golgi modifies and packages proteins for export out of cell. The ribosomes attached to the rough ER act as a site for protein synthesis. They are both part of the endomembrane system.
Why does the Golgi apparatus modify proteins?
Figure 1: The Golgi apparatus modifies and sorts proteins for transport throughout the cell. Proteins must make their way through the stack of intervening cisternae and along the way become modified and packaged for transport to various locations within the cell (Figure 1).
What organelle modifies transports lipids and proteins?
The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids.
