This video demonstrates protein modification golgi organalle. 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. Proteins translated within the rough endoplasmic reticulum are transferred to the Golgi. From there they are modified and packaged into vesicles for distribution. This section focuses on how the modifications done in the Golgi help to direct this process.
