Golgi Apparatus
Located near the outer side of the endoplasmic reticulum.
Structure
Stack of thin, flat and slightly curved sacs.
Sacs:
Thin in the middle and dilated at the edges.
Not connected to each other.
Function
Process and sort newly synthesized proteins.
Proteins are synthesized on rough endoplasmic reticulum
↓
Packed in carrier vesicles
↓
Reach the innermost sac of the Golgi apparatus
↓
Pass through each sac one by one and are processed during this
↓
Reach the outermost sac
↓
Seggregated according to the destination
↓
Secretory proteins: Packed in secretory vesicles ⟶ Stored ⟶ Upon appropriate signal ⟶ Secreted by the process of exocytosis.
Proteins to be sent to intracellular organelles: Packed in separate vesicles ⟶ go to the respective organelle.
