Golgi Apparatus

The Golgi Apparatus (also known as Golgi Body/Complex) is an organelle found in most eukaryotic cells, including animal cells, plant cells, and fungi cells. It functions to modify, sort, and package proteins and lipids for transport within or outside the cell.

Cis Face

The cis face of the Golgi apparatus is where proteins and lipids enter the organelle. It is located near the endoplasmic reticulum, which is responsible for synthesizing these molecules. At the cis face, substances are received and modified before being sorted for transport to their destinations.

Trans Face

The trans face of the Golgi apparatus is the side that faces away from the endoplasmic reticulum and sends proteins and lipids to their final destination. It is responsible for sorting, modifying, and packaging molecules into transport vesicles that can be delivered to other parts of the cell or secreted outside of the cell.

Cisternae

The Golgi apparatus is a cellular organelle that consists of stacked flattened sacs called cisternae. It is responsible for modifying, sorting, and packaging proteins and lipids that are synthesized in the cell. The Golgi apparatus plays a crucial role in the intracellular transport and secretion of these molecules.

Transport Vesicles

Transport vesicles are small membrane-bound sacs that shuttle molecules between different compartments of the cell. They are formed by budding off from the Golgi apparatus and carry proteins and lipids to their final destination. These vesicles are crucial for maintaining the proper function of the cell.

Secretory Vesicles

Secretory vesicles are a type of transport vesicle that carry proteins and lipids from the Golgi apparatus to the cell surface for secretion. These vesicles fuse with the plasma membrane and release their contents outside of the cell. Secretory vesicles are important for a wide range of cellular processes, such as digestion.
