15 mar 2019 · The Golgi apparatus or Golgi body is often called the cell's packing plant or post office. This organelle modifies, packs and transports important molecules, such as proteins and lipids. The Golgi apparatus is adjacent to the endoplasmic reticulum and is found only in eukaryotic cells.
6 dni temu · Golgi apparatus, organelle of eukaryotic cells that is responsible for transporting, modifying, and packaging proteins and lipids. The Golgi apparatus is made up of a series of flattened, stacked pouches called cisternae and is located in the cytoplasm near the cell nucleus.
17 cze 2019 · Also known as the Golgi complex or Golgi body, the Golgi apparatus is an organelle in eukaryotic organisms that moves molecules from the endoplasmic reticulum to their destination, and also modifies products of the endoplasmic reticulum to their final form.
2 lut 2023 · The Golgi apparatus helps maintain cellular homeostasis by secreting proteins. These proteins are signaling peptides that help induce changes in gene expression in target cells, which regulate levels of metabolites and promote homeostasis.
Scientists have proposed two competing models for protein movement through the Golgi: the vesicular transport model and the cisternal maturation model.
Figure 1. Examples of proteins localized to the Golgi apparatus. GORASP1 is a key protein for maintaining the structure of the Golgi apparatus, especially for the reassembly of the fragmented Golgi apparatus after its breakdown during mitosis (detected in HeLa cells).
Today, scientists know that the endomembrane system includes the endoplasmic reticulum (ER), Golgi apparatus, and lysosomes. Vesicles also allow the exchange of membrane components with a...
